Facility Electrical Protection
Lightning protection, grounding, equipotential bonding
and surge protection are all interdependent disciplines
and the focus of the ERITECH® brand of facility electrical
protection products. Reliable protection of personnel
and structures demands a systematic and comprehensive
approach to minimizing threats caused by transients
and other system disturbances. For instance, no air
terminal can safely capture and arrest the lightning
energy without a dependable route to ground. Equally,
even the most expensive surge protection device
(SPD) will not provide optimum protection if a lowimpedance electrical connection to the ground is not
present. Additionally, a low-impedance ground system
may create hazards to equipment and personnel
alike if equipotential bonding is not in place. These
interdependent disciplines are best applied when
looking at a total facility rather than an individual piece
of equipment or a portion of the facility.
Since no single technology can eliminate the harmful
effects of lightning or induced-surge transients, ERICO
has developed the Six Point Plan of Protection. The
concept behind this plan is a holistic and coordinated
approach that embraces all aspects of effective facility
electrical protection.

Grounding Principles
Introduction
Grounding and bonding are an integral part
of any modern electrical protection system
design.
An effective, low-impedance ground system
is a key element of this system. It is crucial
to help provide personnel safety, as well as
reliable protection for vital equipment and to
minimize interruptions of service and costly
downtime.
With over a century of experience in the
design and manufacture of bonding and
grounding products, ERICO, a single source
provider, offers what we believe is the best
range of long lasting and cost-effective
grounding products available.
Soil conditions and seasonal patterns vary
from site to site, the methods of grounding
need to be considered on an individual basis.

Grounding principles

Basic Definitions

It is a fundamental fact that electricity ALWAYS flows to
the point of lowest potential. The task is to help ensure that
electricity, including faults, lightning and electronic noise,
flows to this point with maximum safety to people, while
maintaining the reliability of equipment. Therefore we must
help ensure the safe, controlled flow of electricity with
minimum voltage drop to earth in all cases.

Ground: A conducting connection, whether intentional
or accidental, between an electrical circuit or equipment
and the earth, or to some conducting body that serves in
place of the earth.
Earth: The conductive mass of the earth, whose electric
potential at any point is conventionally taken as equal
to zero. (In some countries the term “ground” is used
instead of “earth.”)

Grounding Codes and Standards
Grounding needs vary according to function. The grounding
requirements of a power system will vary from those of
electrical equipment, lightning protection or for the proper
function of electronic equipment.

Bonding: The permanent joining of metallic parts to
form an electrically conductive path that will ensure
electrical continuity and the capacity to conduct any
current likely to be imposed.

Proper installation of appropriate grounding systems
requires knowledge of the needs and layout of the
facility. Soil characteristics, grounding conductor materials
grounding connections and terminations, are significant
factors determining the design of a grounding system.
Applicable standards and codes must be applied.

TECHNICAL INFORMATION

The need to ground!
There are important reasons why a grounding system
should be installed.
1	 The most important reason is to help protect people!

While many codes and standards contain minimum
grounding and bonding requirements, the design and
installation of electrical grounding systems is one of the
most important aspects of any electrical distribution system.
However, codes and standards are often misunderstood and
grounding systems subsequently installed improperly.

equipment from unintentional contact with live
conductors.

faults and lightning.

Grounding Principles
Why is Good Grounding Important?

Ground Impedance

The transient nature of lightning with its associated
fast rise times and large magnitude currents mean that
special consideration needs to be given to grounding, for
lightning protection to be effective. Many factors such as
soil resistivity variations, installation accessibility, layout
and existing physical features are all site specific and tend
to affect decisions on grounding methods employed. The
primary aim of a direct strike grounding system is to:

Soil resistivity is an important design consideration. It
varies markedly for different soil types, moisture content
and temperatures and gives rise to variations in ground
impedances.

Short, Direct Ground Connections
The voltage generated by a lightning discharge depends
primarily on the risetime of the current and the
impedance (primarily inductance) of the path to ground.
Extremely fast rise times result in significant voltage
rises due to any series inductance resulting from long,
indirect paths, or sharp bends in the routing of ground
conductors. This is why short, direct ground connections
are important.

•	 Efficiently dissipate lightning energy into the ground
•	 Help protect equipment and personnel

Grounding Principles
Low impedance is the key to lightning protection. All
grounding connections should be as short and direct
as possible to minimize inductance and reduce peak
voltages induced in the connections. The ground
electrode system must efficiently couple lightning surges
into the ground by maximizing capacitive coupling to
the soil. The resistance of the ground itself to lightning
currents must also be minimized. Only when all these
factors are taken into account will maximum lightning
protection be achieved.

Downconductor

Grounding principles

The efficiency of a ground electrode system in coupling
a lightning current to ground is dependent on a number
of factors, including the geometry of the ground
electrode system, the shape of the conductors and the
effective coupling into the soil.

Grounding Principles
•	Good corrosion resistance
Figure 1-A
Distance from
the electrode

Ground Rod

The ground electrode system should be corrosion resistant,
and compatible with other conductors that are buried
and bonded to the ground system. Copper is by far the
most common material used for grounding conductors. In
general, some form of maintenance or inspection procedure
should be adopted to ensure the long-term effectiveness of
a grounding system.

•	Electrically and mechanically robust and reliable
Mechanical coupling can be used to join ground conductors,
but suffers from corrosion effects when dissimilar metals 	
are involved. As well as mechanical strength, CADWELD®
connections provide excellent low impedance, long life
electrical connections with excellent corrosion resistance.

Ground Resistance

TECHNICAL INFORMATION

Grounding principles

Figure 1-B

Figure 1-B illustrates current flow from the injection
point of a single ground electrode. As current flows out
from the central injection point, a voltage gradient on the
ground surface around the electrode is produced. This
gradient levels off to a plateau at some distance from the
electrode, as seen in Figure 1-A. The impedance seen
by the current is determined by the soil particles in direct
contact with the surface of the rod, and by the general
impedance of the soil.

When current flows from a ground electrode into the
surrounding soil, it is often described as flowing through a
series of concentric shells of increasing diameter.
Each successive shell has a greater area for current flow
and consequently, lower resistance. At some point distant
from the earth conductor the current dissipation becomes
so large and current density so small, that the resistance is
negligible.
In theory, the ground resistance may be derived from the
general formula:

R = P L	 Resistance = Resistivity x Length
A
Area
			

Characteristics of a Good Grounding System
•	Good electrical conductivity
•	Conductors capable of withstanding available
electrical fault currents

This formula illustrates why the shells of concentric earth
decrease in resistance the farther they are from the ground rod:

R = Resistivity of Soil x Thickness of Shell
Area
			

•	Long life — at least 40 years
•	Low ground resistance and impedance
The basic philosophy of any grounding installation should
be an attempt to maximize the surface area of electrodes
or conductors with the surrounding soil. Not only does
this help to lower the earth resistance of the grounding
system, but it also greatly improves the impedance of the
grounding system under lightning surge conditions.
•	Equipotential bonding
Equipotential bonding helps ensure that hazardous
potential differences do not occur between different
incoming conductors such as metallic water services,
power systems, telecommunication systems and the
local ground, and also minimizes step and touch
potentials.

In the case of ground resistance, uniform earth (or soil)
resistivity throughout the volume is assumed, although this
is seldom the case in nature. The equations for systems of
electrodes are very complex and often expressed only as
approximations. The most commonly used formula for single
ground electrode systems, developed by Professor H.R. Dwight
of the Massachusetts Institute of Technology, is the following:

ρ
R = __	
2πL	

{(ln 4L) - 1}
r

R = resistance in ohms of the ground rod to the earth (or soil)
L = grounding electrode length
r = grounding electrode radius
ρ = average resistivity in ohms-cm.

Grounding Principles
Conditions Influencing Soil Resistivity
The resistance of the earth itself (soil resistivity) can
significantly impact the overall impedance of the grounding
system. Several factors, such as soil composition, moisture
content, mineral content, contaminants, etc., determine the
overall resistivity of the earth.

The Four-Point Method

U.S. Bureau of Standards Technical Report 108

1. Four test stakes are positioned in a straight line an equal
distance apart and are hammered into the ground to be
surveyed to a depth of not more than 1/20 the distance
between the adjacent stakes.

Soil Resistivity Testing
To properly design a grounding system, it is essential to
test soil resistivity. Several methods can he used to measure
earth resistivity: the four-point method, the variation
in-depth method (three-point method) and the two-point
method. The most accurate method and the one that
ERICO recommends is the four-point method.

2. An earth resistance tester is connected to these four
stakes as shown in Figure 2.
3. The DC test option on the tester is then selected and
performed, and the resistance figure “R” recorded.
4. The soil resistivity level “r” (in ohms/cm) is then
calculated using the formula: r=2paR where:
	
	

R = the resistance figure, in ohms
a = the separation of the test stakes, in meters.

Where:
A = distance between the electrodes in centimeters
B = electrode depth in centimeters
If A > 20 B, the formula becomes:
p = 2π AR (with A in cm)
p = 191.5 AR (with A in feet)
p = Soil resistivity (ohm-cm)
This value is average resistivity of the ground at a depth
equivalent to the distance “A” between two electrodes.

Grounding Principles
Grounding / Earthing System Design

A proper facility grounding system incorporates these
necessities in the most cost-effective manner that will last
for the design life of the facility.

Grounding systems are important. It is not expensive
to build an appropriate ground system during initial
construction of a facility, but it can be very expensive to add
to it, enhance it, or replace it after the facility is complete.
Care should be taken to design a system that is appropriate
both for clearing ground faults and dissipating lightning
energy. The system must have a long performance life,
meet applicable codes / standards for safety, and have
sufficient bonding points to make it easy to add new
equipment / facility grounding to it easily.

ERICO is a manufacturer and marketer of grounding,
bonding, lightning protection and surge protection
products and systems. ERICO has many knowledgeable
and experienced engineers on staff with the training and
the tools (including some of the latest design software) to
design appropriate grounding systems. These engineers can
assist facility owners, engineers and contractors in designing
the most appropriate system for the facility in question.
Grounding Chain

Design considerations include:

	1. Grounding Electrode Conductor

•	Purpose of facility
•	Design life of facility
•	Soil resistivity at 3 depths
•	Corrosive nature of soil
•	Shape and available area of facility site
•	Existing structures and their grounding systems
•	Seasonal variations in moisture and temperature for
facility site
•	Public access & personnel use
•	Adjacent facilities and electrical systems
•	Future uses, additions, equipment for facility

	2. Grounding Connections
	3. Grounding Electrode
	4. Electrode to Soil Resistance

For proper operation of overcurrent devices, it is important
to have a low DC ohmic resistance to remote earth. In
many instances, this is best achieved by installing a deep
ground electrode on site. It should be driven deep enough
to reach the permanent water table.
For dissipation of direct or indirect lightning currents, it
is better to have many horizontal ground conductors in
the soil, preferably in a radial array. This provides a low
impedance path of dissipation to the high frequency
component of the lightning energy.
For personnel, particularly where people congregate or
where equipment operators will be located, it is important
to have a grid system or other equipotential plane to reduce
“step potential” and have equipment and metal structures
bonded to the ground system to reduce “touch potential”.

Grounding Principles
The Grounding Chain
The performance of the grounding system is determined by
the quality of the following five components all of which
are of equal importance.
1. The Grounding Electrode Conductor. Typically made
from copper or copper-bonded steel, the grounding
electrode conductor must be large enough to withstand
the maximum available fault current over the maximum
clearing time.

TECHNICAL INFORMATION

Grounding principles

2. The Grounding Connections. Often overlooked, the
grounding connections are used to tie the elements of
the electrode system together. Exothermically welded
connections provide a molecular bond that will never
loosen or corrode. Mechanical connectors, such as
crimp, bolted, and wedge type, rely on physical pointto-point surface contact to maintain the integrity of
the electrical connection. IEEE® Standard 837 provides
detailed information on the application and testing of
permanent grounding connections. ERICO can provide
an independent, third-party test report evaluating the
performance of these connectors in accordance with
the testing procedures set forth in IEEE 837 Standard for
Qualifying Permanent Substation Grounding Connections.

and to determine the depth of the conductive soil so that
electrodes can be placed accordingly.
T he grounding system will carry little or no current for long
periods of time until a fault occurs or a lightning strike
or other transient requires dissipation. At that point, the
grounding system components will be expected to perform
like new while conducting large amounts of current.
Most of the grounding system is concealed below grade,
making inspection of the grounding components difficult
or impossible. The underground environment is a harsh
one. The initial selection of the components used in the
grounding system is of critical importance to its long-term
effectiveness.

3. The Grounding Electrode. The grounding electrode
provides the physical connection to the earth and is the
instrument used to dissipate current into it. There are
two main types of electrodes. “Natural” electrodes are
intrinsic to the facility and include metal underground
water pipe, the metal frame of the building (if effectively
grounded), and reinforcing bar in concrete foundations.
“Made” electrodes are installed specifically to improve
the performance of the ground system and include wire
meshes, metallic plates, buried copper conductor and
rods or pipes driven into the ground. The ground rod is
the most widely used electrode.

CADWELD®
Exothermic
Connection

4. Electrode to Soil Resistance. Amount of rod surface and
rod replacement are the controlling factors. Doubling
diameter reduces resistance by only 10% and is not cost
effective. Doubling rod length, however, theoretically
reduces resistance by 40%. The most common solution is
proper placement of multiple rods that are driven to the
required depths.

5. The Soil. The soil resistivity, measured in ohm-centimeters
or ohm-meters, plays a significant role in determining
the overall performance of the grounding system and
must be known before a proper grounding system can
be engineered. Measuring soil resistivity allows the design
engineer to locate an area with the most conductive soil

Ground System Components
Ground Electrodes
The ground electrode is a critical component of the grounding system. Many different types of electrodes
are available, some “natural” and some “made”. The natural types include metal underground water
pipe, the metal frame of a building (if effectively grounded), a copper wire or reinforcing bar in a
concrete foundation or underground structures or systems. Consideration should be given
to bonding of natural earths to ensure electrical continuity with a facility’s other “earths”.
“Made” electrodes are specifically installed to improve the system grounding or
earthing. These earth electrodes must ideally penetrate into the moisture
level below the ground level to reduce resistance. They must also consist
of metal conductors (or a combination of metal conductor types), which
do not corrode excessively for the period of time they are expected to serve.
Made electrodes include rods or pipes driven into the earth, metallic plates
buried in the earth or a copper wire ring encircling the structure.
Underground gas piping or aluminum electrodes are NOT permitted for
use as ground electrodes.

Ground Rods Which ground rod should be used?

Galvanized steel rods are one of the cheapest electrodes
available. However, they are not the most cost effective
since they have a relatively short service life. Solid copper
and stainless steel rods have a long service life. However,
they are considerably more expensive than galvanized steel
rods. In addition to this, solid copper rods are not suited
to deep driving or even driving short lengths into hard
ground, without bending.

The photo on the left shows two ground rods that were
driven into the soil vertically at the Pecos testing site in
Las Vegas, NV in December of 1992. The top ground
rod is galvanized steel, 3/4” x 10’. Bottom ground rod
is copper-bonded, 5/8” x 8’. Both ground rods were
exhumed from the site in April of 2004. The loss of zinc
resulted in excessive corrosion of the steel. The copperbonded steel ground rods showed minimal corrosion.

Copper-Bonded Ground Rod
The copper-bonded ground rod has an electrolytic
coating of copper deposited over a layer of nickel. This
process ensures a long lasting, molecular bond between
the copper layer and the steel core. ERICO recommends
copper-bonded ground rods because the copper coating
will not slip or tear when driven, nor will it crack if the
rod is bent. The tough, carbon steel core has good
characteristics for deep driving. Copper-bonded ground
rods have a high resistance to corrosion and provide
a low resistance path to ground.

The Stainless Steel Ground Rod Option
Excavated after 12 years.

It is important to note that certain soils and land fill areas
may not be compatible with copper. In these situations,
stainless steel is a better proposition. Stainless steel may
also be an alternative, where structures or components,
such as steel towers, poles or lead sheathed cables are
in close proximity to an array of ground electrodes. In
these circumstances, consideration must be given to
the consequence of galvanic corrosion. The high cost of
stainless steel rods prohibits their widespread use.

Conductors
There are two basic criteria for grounding conductor
selection:
1. 	The physical characteristics of the conductor must be
of a robust nature, sufficient for the environment.

Grounding SYSTEM COMPONENTS

GROUND CONDUCTORS

2. 	The cross sectional area of the conductor must be of
	 sufficient size, so that it shall successfully conduct the
	 maximum fault current for a period, which allows
	 the operation of protection equipment (or the
	 dissipation of this energy).

Physical Characteristics
The most common ground conductor is a soft drawn,
stranded copper conductor. Flat copper strip / tape is also
popular because it offers a large surface area, resulting in
lower impedance.

Bare Copper & Tinned Copper

In some circumstances, the maximum fault current for the
installation is small. While a conductor of correspondingly
small size could be used, a minimum cross section, often
set by the governing authority or applicable standards
body (to minimize potential damage likely to occur from
any future excavation on the site), is applied.

Ground Rods and Couplers
Ground Electrodes
Ground Rod Accessories and Application
ERICO, a leading manufacturer of UL® listed copperbonded ground rods, offers a complete range of
rods, driving sleeves and studs, rod coupling methods
and connections for reliable grounding in nearly any
application.

Driving Sleeves
The driving sleeve
fits over the
pointed ground
rod to protect
the rod end from
“mushrooming” as
the ground rod
is driven into earth.

Grounding SYSTEM COMPONENTS

GROUND RODS AND COUPLERS

Ground
Rods
Ground Rod
Diameter and
Length

Compression
Coupling

Ground rod
diameter
must also be
considered.
Although larger
diameter rods
are more rigid
and less prone to whip or bending, they may have a
greater drag than smaller diameter rods when being
driven. It must also be noted that increasing the ground
rod diameter has relatively small impact on grounding
system resistance when compared to length. Standards
nominate a minimum diameter or periphery and thickness
if not cylindrical, mainly based on mechanical strength.

Couplings enable
ground rods to
be driven quickly
and easily without
the risk of rod
separation. They are
generally tapered so
when the rod is driven
into the coupling, the two
parts compress to form
a conductive connection.

Threaded
Coupling

In general, lightning protection standards recommend
copper-bonded electrodes of specified diameter. Standard
UL 467 requires a minimum rod length of 8’ with a
minimum diameter of 0.50” and 10 mils of copper.

Threaded couplings
allow for full contact
of the rod point
with the butt end of
the preceding rod.

Other standards may nominate a specific resistance for
the installation. If space is limited, the contractor may be
required to install electrodes to a depth that achieves the
required value.

Chemical Ground Electrodes
Chemical ground electrodes, part of the ERITECH® line of
Facility Electrical Protection products from ERICO, provide
a low impedance ground in locations of high soil resistivity
and dry soil conditions. Used in conjunction with a bentonite
backfill and ERICO’s unique GEM material, the ERITECH brand
of chemical ground electrode system provides a method to
improve soil resistivity directly surrounding the electrode, and
can replace multiple conventional ground rods. It maintains
a low ground resistance, maintenance-free installation that
dissipates lightning energy and other dangerous electrical
fault currents, even in sandy or rocky soil conditions. The
chemical ground electrode is useful for providing an effective
earth in poor soil conditions where space for electrodes is
limited. Market applications include telecommunications,
power generation and distribution, commercial and industrial,
manufacturing, transporation (rail and aviation), lightning
protection, recreational facilities, and defense.
ERITECH brand of chemical ground electrodes are most
effective when installed as part of a total system that includes
high conductivity backfill materials, access/inspection wells,
and permanent, reliable CADWELD® connections. They may
be installed either vertically or horizontally.

Ground Enhancement Material

Ground Enhancement Material
(GEM)
To improve the conductivity of a grounding system,
ERICO recommends using Ground Enhancement Material
(GEM).

Developed in 1992, Ground Enhancement Material
(GEM) is a superior conductive material that solves your
toughest grounding problems. It is the ideal material to
use in areas of poor conductivity, such as rocky ground,
mountain tops and sandy soil. GEM is also the answer in
situations where ground rods can’t be driven or where
limited land area makes adequate grounding difficult
with conventional methods. Only rarely do grounding
system designers and contractors get to work on a site with
good grounding conditions. Even under ideal circumstances,
soil structure can vary and make it difficult to achieve
uniform, low levels of resistivity across a wide area. Under
almost all soil conditions, the use of a ground enhancement
material will improve grounding effectiveness. Some are
permanent and require no maintenance. When selecting a
ground enhancement material be sure it is compatible with
the ground rod, conductor and connection material.

GEM is a low-resistance, non-corrosive, carbon dust based
material that helps improve grounding effectiveness,
especially in areas of poor conductivity. GEM contains
cement, which hardens when set to provide a permanent,
maintenance-free, low-resistant grounding system that
never leaches or washes away. GEM does not adversely
affect soil and will not leach ions or contaminate ground
water. It meets all EPA requirements for landfill (USA).
A Material Safety Data Sheet (MSDS) is available on
request.

Grounding SYSTEM COMPONENTS

ERICO provides 25 lbs of Ground Enhancement Material
(GEM) in a convenient, easy to handle bucket container.
Just pour the required amount of clean-potable water
into the bucket and mix to create a slurry form. Then
proceed to pour the slurry mixture into the hole or
trench.

1. Premix GEM into a slurry form. Use 1.5 to 2 gallons
(5.7 to 7.6 liters) of clean-potable water per bag or
bucket of GEM. To mix GEM into a slurry form, use
a standard cement mixer or mix in a mixing box,
wheelbarrow, etc. Use 1.5 to 2 gallons (5.7 to 7.6
liters) of clean-potable water per bag of GEM. Do not
mix GEM with salt water.
2. Spread out enough GEM to uniformly cover bottom of
trench–about 1 inch (2.5 cm) deep. (See Table)

3. Place conductor on top of GEM. (See Note 1)
4. Spread more GEM on top of conductor to completely
cover conductor – about 1 inch (2.5 cm) deep. Allow
GEM to harden. Wait 30 minutes to one hour before
filling the trench with soil backfill.

Ground Enhancement Material
Ground Rod Backfill Installation:
1. Auger a 3-inch (7.5 cm) or larger diameter hole to a
depth of 6 inches (15 cm) shorter than the length of
the ground rod.

Hole

2. Place ground rod into augered hole and drive 1 foot
(30 cm) (if possible) into bottom of the hole. The top
of the ground rod will be approximately 6 inches (15
cm) below grade. At this time, make any connections
to ground rod using CADWELD® connections. (See
Note 1)

3. Premix GEM into a slurry form. Use 1.5 to 2 gallons
(5.7 to 7.6 liters) of clean-potable water per bag or
bucket of GEM.

4. Pour the appropriate amount of GEM (see table)
around the ground rod. To ensure the GEM material
completely fills the hole, tamp around the ground rod
with a pole. Wait 30 minutes to 1 hour before filling
the hole with soil backfill.

Note 1: 4
 inches (10 cm) of insulating material should be
applied to the conductors and ground rods exiting the
GEM, starting 2 inches (5 cm) inside the GEM.
Note 2: 	Excess standing water must be removed from the hole.

EQUIPOTENTIAL BONDING

Grounding Bus Bars

Proper bonding is essential to create an equipotential
plane between service grounds and equipment during
fault and transient conditions. This equipotential
plane provides a near zero voltage differential and
serves to protect people and equipment during these
events. The most popular bonding product in use
today is the ground bar or bonding bar. Ground bars
provide a convenient, single-point grounding and
bonding location. Conductors are welded to the bar

using a CADWELD® exothermic connection or are
mechanically fastened by using lugs.
ERICO can design and manufacture custom bars. In
addition, the breadth of the product offering includes
TMGB bars, which meet the requirements of TIA®/
EIA® 607 and conform to BICSI® recommendations.
Our perimeter bus system allows for fast and
easy field installation of halo and other perimeter
grounding schemes.

Signal Reference Grid (SRG)

The importance of SRGs for
Computer Applications
In order to minimize the effects of noise,
many computer manufacturers, users
and government agencies have detailed
specifications regarding computer
grounding. Computer installations are
particularly sensitive to:
• 	Coupling between adjacent power, data
circuits and ground, where noise can be
introduced into cables — even nearby
lightning strikes can be a real threat.
• 	Noise levels from nearby transmitters
may be a serious problem and require
shielding.

Components of the SRG
Signal Reference Grid (SRG)

Effective SRG uses:
•	A multitude of conductors to create a very low
impedance to noise at any frequency
•	2-foot spacing between conductors
•	Terminations that provide a constant impedance over
the life of the facility
•	Multiple paths within the SRG to allow the noise
currents to divide at each crossover, which further
reduces voltage drop
•	A mesh made of flat copper strips to provide the most
functional low impedance and cost effective computer
grounding system available
•	Welded connections to assure a noise-free bond

Welded connections are often specified because they
are the only connections proven to assure a “noisefree” bond. Normal shock and vibration jar mechanical
connections, creating electronic noise. This causes
relatively high Ldi/dt voltages, due to a sudden change
in connection impedance. This sudden change can
result in pulses which can be coupled onto the signal
circuits. These unwanted signals can create false data
or even cause permanent circuit damage. Corrosion,
dirt and cleaning fluids cannot interfere with the
molecular bond of a welded joint.

EQUIPOTENTIAL BONDING

Welded Connections

Signal Reference Grid (SRG)
The Signal Reference Grid (SRG) is a pre-fabricated, low
impedance network of conductors established to create
an equipotential plane for high frequency, low voltage
digital signals in such applications as intensive computer,
telemetry and telecommunications installations.

Proper grounding and bonding of sensitive electronic
systems, including computer installations, requires careful
consideration of all frequencies from DC to over 100
megahertz. The local requirements for electrical fault
current and lightning protection must also be met.

Digital signal line voltages are typically low. Their
sensitivity to transient noise is very high (typically 1 volt
for some digital systems). The SRG complies with IEEE®
Standard 1100-1992 for grounding practices in sensitive
electronic environments.

The safety grounding system required by code does not
address the special requirements of noise immunity. An
additional “grounding” system called the Signal Reference
Grid (SRG) is needed for trouble-free equipment
performance.

Bonding Devices
Arc Weldable Bonds
Arc weldable bonds are 4-ft pieces of concentric
cable (19-strand) which are flash-welded to steel rod
for a bonding connection to structural steel and to rebar. Arc
weldable bonds are an economical alternative to exothermic
welding when only a few connections need to be made and an
arc welder is available on site. The rod is sized to match the
ampacity of the cable for fault currents. Complete instructions
are provided.

* Made to exact pipe size. Add nominal pipe size
mold to part number.

Example for CADWELD® Mold Part Numbering:
1.	A 4” outside-diameter pipe is a 31/2” nominal pipe
size. The mold part number for a 4/0 concentric
conductor to this pipe would be:

VSC2Q V 3.50
Base number
(for flat surface)

For vertical

2.	 A nominal 2 x 21/4” H section uses mold code PH2.
	 A 4/0 Type VB weld to this post would be 		
	VBC2QPH2.
