Known  as  a  “testing  laboratory”  with  a  strong  regional 
presence in the Midwest, High Voltage Testing and Safety 
Products (HV) was purchased  by Irby  in February of 2007.  
At  the  time  HV  was  implementing  a  new  strategy  to  re-
position and re-brand itself in the market place. With the 
acquisition, we were able to implement our new strategy of 
being a one-stop, complete Personal Protective Equipment 
(PPE)  supplier  with  the  goal  of  establishing  ourselves 
nationally.  Since the purchase we have been working with 
Irby  marketing,  sales  and  branch  operations  to  integrate 
our  products  and  services  to  an  expanded  network  of 
customers and branches. 
HV  currently  has  two  primary  locations  —  Fargo,  North 
Dakota,  which  serves  as  the  main  warehouse  /  testing 
laboratory and Minneapolis, Minnesota which operates as 
a sales office.  In addition to these locations, HV supports 
and provides all testing services, PPE clothing systems and 
related products to all the Irby branches nationally.
High Voltage Value Model
The HV value model is based on a three-layered approach 
to  electrical  safety  and  protection.    The  three  layers  are 
(1) Rubber Insulating Gloves and Equipment (2)  Arc  Flash 
Protection (3) Flame Resistant (FR) Clothing.  This is shown 
in the “safety triangle” diagram that was developed based 
on Maslow’s hierarchy of needs and being “actualized” or 
in your case “safe” from an electrical discharge of energy.  
The goal being to communicate that if you are missing any 
one  of  the  layers,  then  you  are  at  risk  from  an  electrical 
shock or arc flash blast.  This PPE value model is supported 
by our NAIL Certified Testing Laboratory where we follow 
stringent ASTM and ANSI standards.  The value model has 
application  across  all  markets  including  Utility,  Industrial, 
Contractor and Commercial business segments.
Standards and Regulations Driving the Industry
Safety requirements and regulatory issues will continue to 
significantly impact the electrical industry as enforcement 
and compliance become more stringent. Many of them have 
been  recently  updated  or  are  in  the  process  of  revisions. 
These  standards  affect  all  electrical  workers  across  all 
industries and utilities.
National Fire Protection Association (NFPA) 70E and 
Arc Flash
NFPA  70E  is  one  of  the  various  documents  comprising 
the National  Electric  Code  published by the National  Fire 
Protection Association.  Its intent is to protect workers in 
every industry around any device capable of generating an 
arc flash or electrical shock.
•Arc Flash is a sudden release of electrical energy through 
the  air  when  a  high  voltage  gap  exits  and  there  is  a 
breakdown  between  conductors.  An  arc  flash  gives  off 
thermal radiation and bright, intense light that can cause 
burns. Temperatures have been recorded as high as 35,000 
degrees Fahrenheit. An arc flash can be spontaneous or 
result from inadvertently bridging electrical contacts with 
a conducting object. Other causes may include dropped 
tools or the buildup of conductive dust or corrosion.
•High voltage arcs can also produce considerable pressure 
waves by rapidly heating the air and creating a blast. The 
pressure burst can hit a worker with great force and send 
molten metal droplets from melted copper and aluminum 
electrical components great distances at extremely high 
velocities.  
It is important that you establish an electrically safe work 
condition  before  working  on  a  circuit  or  any  energized 
equipment.  To  create  an  electrically  safe  work  condition 
you should: 
  (1) Identify all power sources 
  (2) Interrupt the load and disconnect the power 
  (3) Visually verify that the disconnect opened the circuit 
  (4) Lock-out and tag-out the circuit 
  (5) Test for voltage 
  (6) Ground all power conductors  
All these steps require the use of appropriate PPE for shock 
and  arc  flash  protection  including  voltage  rated  gloves, 
Flame  Resistant  (FR)  work  clothes,  arc-rated  face  shield, 
flash suits with hoods and safety glasses.  
National Electric Safety Code (NESC) 2007   
The 2007 National Electric Safety Code has given power and 
communications utilities until January 1, 2009 to determine 
the  potential  exposure  to  energy  and  electric  arcs  for 
employees who work on or near energized electrical lines 
and equipment. Employees are required to wear clothing 
or clothing systems with an effective arc rating greater than

the anticipated level of energy.  Furthermore, if the potential 
employee  exposure  is  greater  than  2  cal/cm2  the  employer 
shall require employees to wear clothing or clothing systems 
with an effective arc rating.  In order to comply, utilities must 
determine  the  expected  levels  of  potential  arc  energy  for 
employees performing the work and choose appropriate PPE 
to match the arc energy requirements.  
New OSHA Ruling regarding PPE
As  of  May  15,  2008  all  employers  should  be  in  compliance 
with the new OSHA rule that all PPE must be provided by the 
employer at no cost to the employee.  The final rule clarifies 
OSHA’s requirements regarding payment for employee-owned 
PPE and replacement PPE and indicates it must be provided to 
the employee at NO COST.
Who is responsible for Safety? 
•Employer  -  responsible  for  complying  with  OSHA  require-
ments, the Electrical Safety Program, Safety Policies / Proce-
dures and Safety Training  
•Employee - responsible for adhering to the procedures 
•Owner - responsible for contractors on their jobsite
Safety Facts (From WH Salisbury)
•  Electrical  Safety  is  the  most  over-looked  employee  work 
hazard
•  An  estimated  30,000  non-fatal  electrical  shock  accidents 
occur each year or 3.5 per hour
• 600 people die from electrocution each year
•  Electrocution is 4th in work related fatalities with the majority 
of these incidents occurring at 600 volts or less
•  Approximately  3,000  reported  flash  burn  incidents  are 
reported annually from an arc flash and ignition of flammable 
clothing
• 350 deaths related to arc flash or blast occur each year
How  can  HV  help  ensure  that  I  comply  with  electrical 
safety standards?
HV  offers  a  complete  one-stop  safety  solution  for  all  your 
electrical PPE and training needs. Based on our three-layered 
approach to complete electrical safety coverage, supported by 
our certified testing service, we can help ensure the safety of 
your electrical workers.  
HV services include:
Testing Services
High Voltage Testing and Safety Products is accredited by North 
American  Independent  Laboratories  (NAIL)  for  protective 
equipment testing and we are capable of testing with voltages 
from 500 to 100,000 volts.  All equipment is tested according to 
the latest American Society for Testing and Materials (ASTM) 
and American National  Standards  Institute  (ANSI)  standards.  
We test all types of rubber insulating gloves, sleeves, blankets 
and  line  hoses.    We  can  also  test  all  types  of  tools  such  as 
hot  sticks,  grounding  equipment  and  jumper  cables.    It  is 
important that you re-test your  equipment according to the 
schedule below.  
Arc  Flash  Suits  and  Flame  Resistant  (FR)  Daily  Wear 
Clothing
The type of PPE you provide your  workers  is  determined  by 
the  type  of  electrical  work  you  perform,  your  overall  safety 
program and whether you use sub-contractors for some of the 
work. 
As a general guideline, you should consider the following:  
•All under garments should be of natural fibers such as cotton, 
wool or silk
•Flame  Resistant  (FR)  daily  wear  shirts  and  pants  are 
recommended  for  qualified  and  un-qualified  workers  if 
there  is  a  high  or  constant  level  of  exposure  to  energized 
equipment
•Use Arc Flash suits and hoods for higher levels of safety or 
if you  will  be  testing,  de-energizing  or turning  equipment 
back on.  
It  is  critical  from  a  safety  standpoint  that  the  appropriate 
PPE be worn at all times when working on or near energized 
equipment.  All electrical  work  should  be  done  by  qualified 
personnel  and  an  assessment  of  the  electrical  hazard  level 
performed.  All  PPE  should  have  labeling  identifying  the 
cal/cm2 rating or hazard risk category (HRC) of each item.
Rubber Insulated Gloves and Equipment
Rubber  insulating  equipment  is  your  first  line  of  defense 
from electrical shock. HV carries a complete line of rubber

insulating gloves, sleeves, blankets and line hoses. If something 
fails during the testing process we can provide a replacement 
immediately.  We  can  replace  a  single  glove  or  a  pair.  Your 
life depends on your rubber protective equipment. The level 
of  protection  that  rubber  gloves  provide  depends  on  their 
condition.  It is the responsibility of the user to maintain their 
gloves and other insulating equipment in good condition.

Emergency Disaster
Hurricane season is June 1 - November 30
14
How  prepared  are  you  to  handle  the  affects  of  a  natural 
disaster? Natural  disasters  come in many forms:    hurricanes, 
tropical  depressions,  storm  surges,  high  winds,  tornadoes 
and flooding – affecting communities  and  businesses  in the 
Southeastern United States.  
Professor Gray, of the University of Colorado, forecasted the 
Atlantic  and  Gulf  Coast  2008  hurricane  season  to  be  more 
active than usual. Conditions in the Atlantic are very favorable 
for  an  active  hurricane  season  because  of  the  continued 
increase of the Atlantic water temperature.  The 2008 forecast 
of named storms is 15 and the number of hurricanes is eight 
with an estimated 44% chance that a category 3, 4 or 5 will 
make landfall on the Gulf Coast.

supplies most commonly destroyed and replaced during and 
after a natural disaster.  Use the following list as a reminder to 
help you be prepared before a storm affects you:
Businesses  and  industries  can  limit  injuries  and  damages 
and  return  more  quickly  to  normal  operations  if  they  plan 
ahead.  Emergency  Management  is  the  process  of  preparing 
for,  mitigating,  responding  to  and  recovering  from  an 
emergency.
•  It enhances a company’s ability to recover from financial 
losses, regulatory fines, loss of market share, damages to 
equipment or products or business interruption.
•  It enhances a company’s image and credibility with 
employees, customers, suppliers, and the community.
•  It may reduce insurance premiums.

Top 10 2008 NEC Change Rules
  1. 210.4 Multiwire Branch Circuits
     The rule for “Simultaneous Disconnecting Means” requirements for multiwire branch circuits was expanded.
(B) Disconnecting Means. Each multiwire branch circuit shall have a means to simultaneously disconnect all ungrounded 
conductors at the point where the branch circuit originates. (See Figure 210.2)
Author’s Comment: Individual single-pole circuit breakers with handle ties identified 
for the purpose,  or  a  breaker  with  a  common internal trip, can be used  for  this 
application [240.15(B)(1)].
CAUTION:  This  rule  is  intended  to  prevent  people  from  working  on  energized 
circuits they believe are disconnected.
Analysis:  Multiwire  branch  circuits  can  offer  unexpected  shock  hazards  when 
work is being done on them unless all ungrounded conductors from the multiwire 
branch  circuit  are  disconnected  simultaneously.  This  revised  section  requires 
each  ungrounded  conductor  of  a  multiwire  branch  circuit  to  be  disconnected 
simultaneously  by  common  trip  2-pole  or  3-pole  circuit breakers  or  single-pole  circuit  breakers  with  an  identified 
handle tie.
  2. 210.8 Ground-Fault Circuit-Interrupter Protection for Personnel (GFCI)
      Outdoor GFCI-protection requirements for 15A and 20A, 125V receptacles at nondwelling unit occupancies were 
revised.
(B) Other Than Dwelling Units
(4) Outdoors - All 15A and 20A, 125V receptacles installed outdoors shall be GFCI-
protected. (See Figure 210–10) 
 Analysis:  The  2005  NEC  only  required  15A  and  20A,  125V  “outdoors  in  public 
spaces—for the purpose of this section a public space is defined as any space that 
is for use by, or is accessible to, the public” to have GFCI protection. This change 
now requires GFCI protection for these types of receptacles installed at all outdoor 
locations,  except  as  provided  by  the  exceptions  for  snow-melting  and  deicing 
equipment and industrial establishments.
By Mike Holt
Know What’s New
In  this  latest  code  cycle,  the  Code  Making  Panels  (CMPs) 
sifted  through  3,688  change  proposals.  Some  of  the 
resulting  changes  were  minor  editorial  revisions.  Others 
were  more  significant,  such  as  new  Articles,  Sections, 
Exceptions, and Fine Print Notes.
Why  does  the  NEC  undergo  revision  every  three  years? 
After all, electricity doesn’t change every three years. For 
one thing, the NEC must keep up with changes in methods 
and  materials  as  technology  marches  forward.  Other 
factors behind those 3,688 proposals include fire data and 
efforts to make the NEC more user-friendly.
Code Change Wrap-up
We’ve highlighted what we consider to be the top 10 code 
changes for the industry in general, but this cycle produced 
hundreds of changes. Which ones really apply to the work 
you  do?  Use  this  simple  three-step  process  to  find  the 
answer:
1.  Review a sampling of typical jobs you did over the past 
year.
2. Note which NEC requirements apply.
3.  Look up those requirements in the 2008 NEC. Compare 
them to the 2005 requirements.
As  you  do  this,  jot  down  some  notes  on  what  you  think 
should be different in the NEC. This will give you the basis 
for  making  change  proposals  of  your  own  for  the  2011 
NEC. You have about a year left to submit those. But that 
time will be gone before you know it, so get started now.

   3. 250.4 General Requirements for Grounding and Bonding
        A new Fine Print Note alerts Code users to the advantage of reducing the length of the grounding electrode conductor.
(A) Grounded Systems
(1) Electrical System Grounding. Electrical power systems, such as the secondary winding of a transformer are grounded to the 
earth to limit the voltage caused by lightning, line surges or unintentional contact by higher-voltage lines.
FPN:  An  important  consideration  for  limiting  the  imposed  voltage  is  the  routing  of 
bonding and grounding conductors so that they are not any longer than necessary to 
complete the connection without disturbing the permanent parts of the installation and 
so that unnecessary bends and loops are avoided. (See Figure 250-4)
Author’s Comment: System grounding helps reduce fires in buildings as well as voltage 
stress  on  electrical  insulation,  thereby  ensuring  longer  insulation  life  for  motors, 
transformers, and other system components.
Analysis: This new Fine Print Note is intended to call attention to the instructions contained 
in Sections 800.100(A)(5), 810.21(E), and 820.100(A)(5) that grounding conductors be run 
as short as possible and as straight as possible. This provides an effective path to the earth 
for line surges caused by lightning events.
  4. 250.32 Buildings or Structures Supplied by Feeder or Branch Circuit
     The rule that permitted the regrounding of the neutral conductor at separate buildings and structures was deleted.
(B)  Equipment  Grounding  Conductor.  To  quickly  clear  a  ground  fault  and  remove 
dangerous  voltage  from  metal  parts,  the  building  or  structure  disconnecting  means 
shall be connected to the circuit equipment grounding conductor of a type described in 
250.118. Where the supply circuit equipment grounding conductor is of the wire type, 
it shall be sized to 250.122, based on the rating of the supply circuit overcurrent device 
rating. (See Figure 250-21)
 Exception: For existing premises, when an equipment grounding conductor was not run 
to the building or structure disconnecting means, the building or structure disconnecting 
means can remain connected to the neutral conductor where there are no continuous 
metallic paths between buildings and structures, ground-fault protection of equipment 
isn’t installed  on the  supply  side  of the  circuit,  and  the  neutral  conductor  is  sized  no 
smaller than the larger of:
  (1) The maximum unbalanced neutral load in accordance with 220.61.
  (2) The rating of the circuit overcurrent device, in accordance with 250.122.
Caution: To prevent dangerous objectionable neutral current from flowing onto metal 
parts [250.6(A)], the supply circuit neutral conductor is not permitted to be connected to 
the remote building or structure disconnecting means [250.142(B)]. (See Figure 250–22)
Analysis:  In  the  2005  NEC,  250.32(B)(2)  permitted  the  neutral  conductor  to  serve  as 
the effective ground-fault current path, this rule was converted into an exception for 
existing premises. Using the neutral conductor to connect metal objects to the effective 
ground-fault current path is a dangerous practice, especially if the neutral becomes open.

   5. Article 708 – Critical Operations Power Systems
     A new article addressing Critical Operations Power Systems was added to the 2008 NEC.
The provisions of this article apply to the installation, operation, monitoring, control, and maintenance of premises wiring 
intended to supply, distribute, and control electricity to designated critical operations areas in the event of disruption to 
elements of the normal system.
Critical operations power systems are those systems so classed by municipal, state, federal, or other codes, by any governmental 
agency having jurisdiction, or by facility en gineering documentation establishing the necessity for such a system. These systems 
include but  are  not  limited  to  power  systems,  HVAC, fire  alarms,  security,  communications,  and  signaling  for  designated 
critical operations areas.
Critical Operations Power Systems are gener ally installed in vital infrastructure facilities that, if de stroyed or incapacitated, 
will disrupt national security, the economy, public health or safety; and where enhanced electrical infrastructure for continuity 
of operation is deemed necessary by governmental authority.
Threats to facilities that may require transfer of operation to the critical systems include both naturally occurring hazards and 
human-caused events.
Analysis: Recent terrorist events and natural disasters, such the World Trade Center attack and Hurricane Katrina, highlighted 
the  need  to  assess  the  adequacy  of  the  National  Electrical  Code  requirements  for  electrical  infrastructure  protection 
and reliability. This new Article 708 was created by a task group developed in response to Homeland Security activity, 
specifically how to keep an emergency system operating for days. The task group was formed to review requirements in 
the NEC and other NFPA codes and standards covering emergency and standby power systems and sources, and signaling 
systems. 
   6. 250.94 Intersystem Bonding Terminal
      A new rule requires an intersystem bonding terminal for communications systems.
An external  accessible  intersystem bonding terminal  for  the grounding and  bonding  of communications systems  shall  be 
provided at service equipment and disconnecting means for buildings or structures supplied by a feeder. (See Figure 250–
39)
The  intersystem  bonding  terminal  shall  not  interfere  with  the  opening  of  any  equipment  enclosure  and  be  one  of  the 
following:
  (1) Terminals listed for grounding and bonding attached to a meter socket enclosure.
  (2) Bonding bar connected to the equipment grounding conductor with a minimum 6 AWG copper conductor.
  (3) Bonding bar connected to the grounding electrode conductor with a minimum 6 AWG copper conductor.
Author’s Comment: According to Article 100, an intersystem bonding terminal is a device that provides a means to connect 
communications systems grounding and bonding conductors to the building grounding electrode system. See (See Figure 
250-39)
Exception:  At  existing  buildings  or  structures,  an  external  accessible  means  for 
bonding communications systems together can be:
  (1) Nonflexible metallic raceway,
  (2) Grounding electrode conductor, or
  (3) Connection approved by the authority having jurisdiction.
Figure 250-39

FPN  No.  2:  Communications  systems  shall  be  bonded  to  the  intersystem  bonding  terminal  in  accordance  with  the 
following:
  • Antennas/Satellite Dishes, 810.15 and 810.21
  • CATV, 820.100
  • Telephone Circuits, 800.100
Author’s  Comment:  All  external  communications  systems  must  be  bonded  to  the  intersystem  bonding  terminal  to 
minimize the damage to communications systems from induced potential (voltage) differences between the systems from 
a lightning event. 
Analysis: This is one of several correlated proposals to improve the requirements related to the intersystem bonding and 
grounding of communications systems. This provides a more accessible, safer means of bonding all systems, such as power 
and communications, together.
  7. 250.52 Grounding Electrodes
The requirements for a concrete-encased electrode now include vertical electrodes as well as what to do when multiple 
isolated concrete-encased electrodes are present.
(A) Electrodes Permitted for Grounding.
(3) Concrete-Encased Grounding Electrode. A concrete-encased electrode is an electrode that is encased by at least 2 in. of 
concrete, located horizontally near the bottom or vertically within a concrete foundation or footing that is in direct contact 
with the earth consisting of one of the following: (See Figure 250–26)
  •  Twenty feet of one or more bare or zinc galvanized or other electrically conductive coated steel reinforcing bars bonded 
together by the usual steel tie wires not less than ½ in. in diameter, or
  • Twenty feet of bare copper conductor not smaller than 4 AWG
 Author’s Comment: If a moisture/vapor barrier is installed under a concrete footer, then the steel rebar is not considered a 
concrete-encased electrode.
Where  multiple  concrete-encased  electrodes  are  present  at  a  building  or  structure,  only  one  is  required  to  serve  as  the 
grounding electrode system. (See Figure 250–27)
Author’s Comments:
  •  The grounding electrode conductor to a concrete-encased grounding electrode isn’t required to be larger than 4 AWG 
copper [250.66(B)].
  •  The concrete-encased grounding electrode is also called an “Ufer Ground,” named after Herb Ufer, the person who 
determined its usefulness as a grounding electrode in the 1960s. This type of grounding electrode generally offers the 
lowest ground resistance for the cost.
Analysis: The requirements for concrete-encased electrodes have been expanded to allow structural steel rebar in vertical 
foundations to be suitable as a grounding electrode, as long as it meets all of the requirements for horizontal structural 
steel rebar electrodes. In addition, the 2008 NEC clarified that in a building or structure where multiple isolated concrete-
encased electrodes are present, such as for spot footings, only one of these “present” electrodes will be required to be 
used. The  purpose of the  NEC [90.1] is  the “practical safeguarding  of persons and property,” and requiring  all of the 
concrete-encased electrodes to be bonded together served no safeguarding purpose.

  8. 406.8 Receptacles in Damp or Wet Locations
     Receptacles installed in wet locations are now required to be weather resistant.
(B) Receptacles in Wet Locations.
(1)  15A  and  20A  Receptacles.  All  15A  and  20A  receptacles  installed  in  a  wet  location  shall  be  within  an  enclosure  that  is 
weatherproof  when  an  attachment  plug  is  inserted  and  all  nonlocking  15A  and  20A,  125V  and  250V  receptacles  in  a  wet 
location shall be listed as weather resistant. (See Figure 406–4)
Exception:  Receptacles  subject  to  routine  high-pressure  washing  spray  may  have  an 
enclosure that is weatherproof when the attachment plug is removed.
Author’s Comments:
  •   Wet locations are those subject to saturation with water, and unprotected locations 
exposed to weather [Article 100].
  •   Exposed  plastic  surface  material  of  weather-resistant  receptacles  must  have  UV 
resistance to ensure deterioration from sunlight does not take place or is minimal. In 
testing, receptacles are subjected to temperature cycling from very cold to very warm 
conditions and then additional dielectric testing. The rapid  transition from  the cold 
to warm temperature will change the relative humidity and moisture content on the 
device and the dielectric  test ensures that this will  not present a breakdown of  the 
insulation properties.
Analysis: The change to this subsection was made in response to concerns that receptacles located outdoors are not always 
protected from detrimental conditions such as low temperatures, exposure to ultraviolet radiation (UV), physical damage, 
etc., and that weatherproof covers and enclosures do not always provide sufficient protection from the elements. The new 
exception allows receptacle covers in high-pressure spray washing areas to be of the type that is weatherproof when the 
attachment plug is removed. When a weatherproof while-in-use cover is used with high-pressure spray cleaning, liquid can 
spray into the enclosure through the cable openings. This change allows the use of a snap cover that does not have a cable 
opening in it while closed.
  9. 406.11 Tamper-Resistant Receptacles in Dwelling Units
     Requirements for tamper-resistant receptacles were added to the 2008 NEC.
In dwelling units, all 15A and 20A, 125V receptacles shall be listed as tamper resistant.
Author’s Comment: This rule applies to receptacles installed behind appliances, above countertops, and other locations out 
of the reach of children.
Analysis:  This  new  section  requires  the  use  of  listed  tamper-resistant  receptacles  for  all  15A  and  20A,  125V  receptacles 
installed in dwelling units.

  10. 310.15 Ampacities for Conductors Rated 0–2,000 Volts
       A new subsection adds ambient temperature adjustments for conduits installed on rooftops.
(B) Tables
(2) Adjustment Factors
(C) Raceways Exposed to Sunlight on Rooftops. The ambient temperature adjustment contained in Table 310.15(B)(2)(c) is 
added to the outdoor ambient tem perature for conductors or cables that are installed in raceways exposed to direct sunlight 
on or above rooftops when applying ampacity adjustment correction factors contained in Table 310.16.
FPN No. 1: See ASHRAE Handbook–Fundamentals (www.ashrae.org) for the average ambient temperatures in various 
locations.
FPN  No.  2:  The  temperature  adders  in  Table  310.15(B)(2)(c)  are  based  on  the  results  of  averaging  the  ambient 
temperatures.
Analysis:  This  new  subsection  requires  the  ambient  temperature  used  for  ampacity  correction  to  be  adjusted  where 
conductors or cables are installed in conduit on or above a rooftop and the conduit is exposed to direct sunlight. The 
reasoning behind this change is that the air inside conduits in direct sunlight is significantly hotter than the surrounding 
air, and appropriate ampacity corrections must be made in order to comply with 310.10.
For example, a conduit with three 6 THHN conductors with direct sunlight exposure that is 3/4 in. above the roof will 
require 40°F to be added to the correction factors at the bottom of Table 310.16. Assuming an ambient temperature of 
105°F, the temperature to use for conductor correction will be 145°F (105°F + 40°F), the 6 THHN conductor ampacity after 
correction will be 43.50A (75A x 0.58). (See Figure 310–5)
Author’s Comment: When adjusting conductor ampacity, use the conductor ampacity as listed in Table 310.16 based 
on the conductor’s insulation rating. In this case, it’s 75A at 90°F. Conductor ampacity adjustment is not based on the 
temperature terminal rating as per 110.14(C).

Utility
New and Improved Wet/Dry 
Hot-stick Tester
Test procedures specified by IEEE and OSHA can seem men-
acing, but not those about how to test live-line tools.
This tester makes it easy for you to “get with the program.” 
It’s based on the original Chance Hot Stick Tester used over 
the years by conscientious utilities, which now has advanced 
their safety programs into uniform regulations.
It’s a common-sense preventive measure for the responsible 
use of insulated tools on energized transmission and distri-
bution lines. 
On-site Portability, Two Voltages Cover the Globe
For compliance with industry standards, this tester features 
wet and dry modes selected by a toggle switch. A portable 
and  self-contained  unit,  the  tester  is  convenient  for  spot 
checks at field jobsites or periodic diagnostics in the work-
shop. It can test up to a 3-inch-diameter of any brand fiber-
glass-reinforced-plastic (FRP) live-line tool. 
Numeric Readout from Analog Meter
In  a  form  one  person  can  carry  and  operate,  the  tester  ac 
tually  performs  the  equivalent  of  full-scale  test  setups  for 
both Wet (75kV per foot) and Dry (100kV per foot). In either 
case, the meter displays the increase in leakage current due 
to placing the meter on a hot stick. This value may be com-
pared  to  the  level  allowable  by  the  individual  utility.  This 
quantitative test result immediately indicates the stick’s true 
leakage condition, inside and out. It detects leakage currents 
due to surface and internal contamination, independent  of 
stray  currents  because  the  tester  is  “zeroed”  while  empty 
before each use.
Wet/Dry Switch Upgrade Available for Old Models
If you own a previous Chance LS-80  or  LS-81  Tester  with  a 
Pass/Fail meter, the Wet/Dry selector-switch circuitry can be 
factory retrofit. Simply contact the Chance Tool Repair Cen-
ter by  phone  (573-682-8748)  or facsimile (573-682-8647). A 
repair-service specialist will assign a Reference Number, give 
you a cost estimate within 48 hours and usually complete the 
job in one to two weeks.
Operating Ease, free Videotape Offer
Simple  to  operate,  the  tester  comes  with  a  Check  Bar  to 
verify the unit is functional before each use. Besides a fully 
illustrated Owners Manual, which must be read and under-
stood before operating the tester, a seven-minute videotape 
is included with each unit. 
Now with switchable modes for easy compliance with industry test specs
For wet or dry testing, unit simply takes overlapping readings 
along the full length of any hot stick up to 3-inch-diameter.
A Dependable Combination
®
Before each use, set the meter needle to zero with nothing in the 
Tester and self-test the Tester with the Check Bar included.

This  innovative  new  product  will  help  differentiate  Thomas  &  Betts 
from the large number of general purpose  cable  tie  manufacturers 
worldwide.    Twist  Tail®  is  a  perfect  complement  to  Ty-Rap®.  This 
product is ideal for the general application user who wants a simple 
cable tie that installs quickly. 
The new “twist-off” tail means no tools and no sharp edges. This 
allows the tail to be easily removed by bending the tail back and 
forth and easily twisting off the tail after the cable tie is installed.  
This valuable, time saving feature allows you to use the “tool-
less” approach to cable ties, as well as work with limited space 
where you cannot fit a cut-off tool.   
TwistTail  makes  tail  removal  easy  with  its  unique,  patent-
pending design but still provides a full 50 lbs. minimum loop 
tensile strength — perfect for any general-purpose cable tie 
application.
The Twist Tail® is available in 7”, 11” and 14” lengths to give 
you a wide variety of bundling options.  It is also available 
in white to differentiate from standard cable ties or in UV-
resistant  black  for  outdoor  applications.  Twist  Tail®  is  UL 
recognized.
When  strength,  aesthetics,  reliability  and  performance 
are  required,  knowledgeable  professionals  turn  to  the 
original and the best source for cable ties and accessories 
— Thomas & Betts.
Catamount® Twist Tail®
The highly anticipated
