General Guidelines for Installation
This section describes the general guidelines, requirements and safety concerns
applicable to all installations of CURRENT’s Broadband over Power Line solution.
Please direct questions or requests for support to your ground supervisor.
Powerline workers must meet both requirements listed below to be allowed to install
the equipment of the CURRENT 5000 and 6000 series:
1. Be qualified to perform work in the utility power zone (see OSHA 1910.269).
2. Receive appropriate CURRENT training specific to the CURRENT 6000 series
(training course CURRENT 6000 F101 – CURRENT 6000 Field Installation of
CURRENT equipment or the equivalent).
2.1
Safety
2.1.1 Crew requirements
Powerline workers must be qualified to perform work in the utility power zone
(OSHA 1910.269) to be able to install the CURRENT BPL equipment listed in
Chapter 1.
2.1.2 Pole Selection Requirements
The National Electrical Safety Code requires that there be a vertical
Communications Worker Safety Zone between the lower limit of the Power Zone
and the upper limit of the Communications Zone (NESC Rule 235C. Vertical
Clearance Between Line Conductors 1. & 4.). NESC Table 235-5 states the
allowable size of the mandatory Communications Worker Safety Zone.
All BPL equipment being installed on a standard pole or riser pole must be
installed in the Power Zone and cannot extend below the Power Zone. Figure
2 illustrates these zones.
Due to the variances in utility pole layouts, it is difficult to specify the exact
dimensions for the BPL equipment layout. The word “approximately” is often
used throughout this install guide. This is to allow the lineperson some flexibility
in the location where the equipment is installed. The BPL equipment should not
be installed in such a way as to impede the climbing of the pole and/or the
maintenance of the utility equipment on that pole. The installation must be done
in accordance with the utility approved standard.

CT Coupler leads are energized at primary voltage. Therefore, they need to
be treated exactly like a primary jumper. If there is inadequate clearance to
install a primary jumper into an area on a pole, then the CT Coupler should
not be installed there.
When mounting with an EMB, it is important to mount the EMB and CT Coupler
so that the hotline clamps can be spaced 70”apart (accepted range is 66” to 74”).
3.4.1 EMB Mount
This configuration is used when mounting the CT Coupler is using the fiberglass
EMB. The EMB is used to mount the Coupler directly to the pole. The steps
below detail how to mount the CT Coupler using the EMB. The EMB can be
used with either the Top Mount configuration (Figure 6, section 3.3.1) or Body
Mount configuration (Figure 7, section 3.3.2). Please refer to section 3.4.2 if it is
necessary to use the optional t-strap on the EMB.
1. Position the EMB so that the CT Coupler hotline clamps can reach the MV
conductor and be separated 70” (acceptable range is 66-74”).
2. Use the appropriate sized through-bolt and washer to secure the top hole of
the EMB as determined by the pole diameter.
3. Use a lag screw or bolt (whichever meets your utility’s standards and
practices) to secure the bottom hole.

Note
A 3” square washer is required to safely secure the CT Coupler to the cross
arm! 3” square washers are part of the truck ready kit if you do not have one
available.
4. The RF and ground wires should be secured to the pole using utility
approved cover to dress the wires.
Note
The ground wires can be secured to the cross-arm and cross-arm support
using tie-wraps. The wires are then dressed down the pole.
Continue with section 3.4.4 to complete the Cross Arm mount installation.
3.4.4 Ground Wires and Pole Dressing
Remove the tie wraps holding the RF Signal and Ground wires together. Dress
the RF Signal Wire and ground wire from the Coupler (or EMB arm) to the pole
using utility approved cover. If using staples, do not staple the wire directly. For
correct operation, maintain a 2-inch minimum bend radius and avoid sharp bends
or kinks in the wire. This is demonstrated in Figure 17.
Note
For cross arm mounts, the ground and RF wires are dressed horizontally
across and then vertically down the pole. The RF wire will be attached to the
CURRENT Bridge OH (Chapter 6).

Connecting to the pole ground (only):
1. If there isn’t a primary neutral, connect the CT Coupler ground wire to the
pole ground using one of the compression H-Tap connectors or other utility
approved connectors per your utility’s standard procedures.
Connecting to primary neutral (only):
1. If there isn’t a pole ground, connect the CT Coupler ground wire to the
primary neutral using one of the compression H-Tap connectors or other
utility approved connectors per your utility’s standard procedures.
Connecting to the pole ground and primary neutral:
1.
If a jumper between the pole ground and primary neutral does not already
exist, inter-connect the primary neutral and the pole ground together using #6
ground wire along with one of the compression H-Tap connectors or other
utility approved connectors per your utility’s standard procedures.
2. If a jumper is already in place, inspect the jumper and make corrections if
needed.
3. Connect the CT Coupler ground wire to the pole ground using one of the
compression H-Tap connectors or other utility approved connectors per your
utility’s standard procedures.
The Drain/ground Wire must be connected to a verified and reliable ground
before the CT Coupler is activated. The pole ground must be shown to be
less than 100 ohms impedance to earth. Failure to connect the RF
Drain/ground wire before energizing the CT Coupler, or to verify the
integrity of the ground connection, could result in serious injury or death.
Installation must be de-energized when the ground wire has come loose,
broken or otherwise disconnected.
¾
The CT Coupler is now installed, but not live. The next step is to install the
CT Backhaul-Point (Chapter 5), the CURRENT Bridge (Chapter 6) or the
CURRENT Gateway-Bridge OH 6030 (Chapter 7).

3.4.5 Bringing the CT Coupler to a Live State
Once the CT Backhaul-Point, the CURRENT Bridge OH, or the CURRENT
Gateway-Bridge has been installed (as described in Chapters 5, 6, and 7
respectively), and the RF wire connected, then the CT Coupler needs to be
brought to the live state. It is important that the hotline clamps be cleaned and
prepped per the manufacturer’s specifications. This is described below. For more
details, please refer to Appendix D for the instruction sheet provided by the
manufacturer.
1. Thoroughly clean the aluminum and copper conductor contact surfaces by
brushing to remove oxides and other foreign matter.
2. Immediately after brushing, generously coat the cleaned portion of the
conductor with inhibitor. Use a high quality joint compound such as
Anderson’s HTJC, Fargo GF178 Inhibitor or Chance’s ZLN Inhibitor.
3. Using either the shotgun stick or gloved hands, attach the hotline clamps to
the primary. The distance range between the two hotline clamps is 66-74
inches. It is highly recommended that the hotline clamps be installed as close
to 70” as possible.
4. Tighten the clamps. If using an inch pound torque, do not exceed 200 lb. in.
If not using an inch pound torque, be sure not to use power tools as this will
cause damage.

3.4.6 Shorten or Lengthen Flying Lead
It is possible that you will need to shorten or lengthen the flying lead in order to
obtain the required distance. It is necessary to keep the overall length the same,
so if you lengthen one lead, then the other will need to be shortened the same
amount.
To lengthen the flying lead length:
1. Cut a piece of the #6 AWG wire to the desired length.
2. Using the crimp sleeve, attach the wire to the existing flying lead.
To shorten the flying lead length:
1. Loosen and remove the bolt which is holding the #6 jumper on the hot clamp.
2. Cut the eyelet off of the jumper.
3. Cut a new piece of the #6 stranded copper leads to the desired length so that
the distance range between the hotline clamps will be as close to 70” as
possible.
4. Remove the insulation from the #6 jumper to the length needed so that it can
be fully inserted into the butt splice and eyelet.

Note
You need to be careful when removing the insulation so as to avoid nicking
or damaging the conductor strands.
5. Crimp both ends of the butt splice.
6. Slide the heat shrink over the conductor butt splice and apply a small amount
of heat to seal it over the conductor.
7. Install the eyelet on the hotline clamp end of the jumper by fully inserting the
#6 stranded conductor, then crimp.
8. Insert the bolt.
9. Attach the jumper eyelet to the hotline clamp and tighten.
Once the first flying lead is attached, then the other lead becomes hot! Use
extreme caution when handling the second lead!

Cable Preparation
The CT Coupler is installed directly over the cable semicon. The CT Coupler is
approximately 3.5” long.
Note
If your utility practice for installing the Coupler entails de-energizing the MV
cable, then before installing the Coupler, it is recommended that you perform
a continuity test to verify that the Coupler is being installed on the proper
cable.
If additional cable jacket and neutrals must be removed to expose sufficient cable
semicon in order to install the CT Coupler, CURRENT recommends that the
cable be de-energized per your utility’s standard operating procedures prior to
installing the CT Coupler.
1. Strip the neutral wires back a minimum of 6”.
2. Once the jacket has been pulled back from the cable, unwind the neutral
wires and fold them back so that they are out of the way. Figure 22 illustrates
an example of how to prep and seal the cable.

1. Ensure that at least 3.5” of the semicon is exposed between the pothead or
termination and the neutral dressing. This is where the CT Coupler will be
installed.
Notes
a) If the cable needs to be resealed, then at least 6” of semicon will need to
be exposed.
b) The Coupler may be placed lower on the cable if required by utility
standards or existing hardware makes it necessary.
2. If there is no need to strip back the jacket or neutrals, and the semicon is
already covered with tape or coldshrink, then the CT Coupler is installed
directly over the existing tape or coldshrink. Continue with step 8.
3. If the cable is jacketed, then 6” of the jacket will need to be removed.
4. Open up the concentric and seal both ends with mastic tape.
5. Install two (2) layers of half lapped plastic electrical tape over the top of the
exposed semicon. Make sure that the electrical tape is installed starting at the
top of the exposed semicon, working down and then back up the semicon.
6. Install a concentric neutral jumper. The end result is shown in Figure 25.

CT Backhaul-Point OH 5000g
This chapter describes the procedure for installing a CT Backhaul-Point OH 5000g.
Please direct questions or requests to your ground supervisor.
The CT Backhaul-Point OH 5000g is the device in a Broadband over Power Line (BPL)
that transfers power line communications signals to the primary distribution line from the
upstream data communications network and vice versa, with communications to the
upstream network via fiber optic cables. It works in conjunction with other components
in a pole assembly.
Powerline workers must meet both requirements listed below to be allowed to install
the equipment of the CURRENT 5000 and 6000 series:
1. Be qualified to perform work in the utility power zone (see OSHA 1910.269).
2. Receive appropriate CURRENT training specific to the CURRENT 6000 series
(training course CURRENT 6000 F101 – CURRENT 6000 Field Installation of
CURRENT equipment or the equivalent).

¾
A few seconds after the last 120 volt power wire is connected, the CT
Backhaul-Point will emit a single tone signifying that it has power. If you do
not hear the beep, check the LV power supply. If the LV power supply is
fine, then change out the unit.
¾
After 30 seconds the CT Backhaul-Point will emit four (4) sequential tones
signifying the CT Backhaul-Point has booted correctly and loaded the
necessary software. These four (4) sequential tones are confirmation that the
CT Backhaul-Point has been properly installed.
¾
You should not have to wait more than two (2) minutes for the entire process
to take place.
Note
If you do not hear the proper tones (or no tones at all) follow your utility
standard procedures for dealing with equipment failures.
Removing Equipment
There is no specific order for removing the CT Backhaul-Point. The simplest
way is to disassemble in the reverse sequence from assembly.
When removing the CT Backhaul-Point, be sure to blunt cut the wires. This will
prevent the possibility of the neutral (white) wire from touching the energized
wire and blowing the neutral fuse.

4. Loosen the lag screw slightly.
5. Hang the Gateway-Bridge on the through bolt. The top mounting plate will
fit on the through bolt. The bottom mounting plate will fit over the lag screw.
6. Secure the Gateway-Bridge by tightening the nut on the through bolt and
then the lag screw.
When connecting the power cables of the CURRENT equipment, it is important
to remember that when only one of the red or black wires is connected, the
unconnected wire will float to the same voltage potential as the wire which is
connected. When both wires are connected, current flow is limited by the
circuitry in the equipment.
7. Cover the exposed wire on the red and black power wires with electrical
tape. This will protect in case of accidental contact with the power wires
before they are connected in step 13.
8. Cut the ground wire to the length needed.
9. Attach one end of the wire to the Gateway-Bridge ground connector using a
screwdriver.
10. Attach the other end of the ground wire to the pole ground or system neutral
conductor with a crimp. Verify that the pole ground and system neutrals are
interconnected.
11. Connect the coax cable from the Coupler to the coax cable on the GatewayBridge.
Always make sure that the unit is properly grounded before connecting or
disconnecting the power cable!

CT LVR OH 5000
This chapter describes the procedure for installing a CT LVR OH 5000. Please direct
questions or requests to your ground supervisor.
The CT LVR OH 5000 is the device in a Broadband over Power Line (BPL) that extends
the reach of the broadband communications on the secondary distribution line. It is used
when the broadband signal is not able to reach a building from the CT Bridge directly.
LVR stands for Low Voltage Repeater. As it name suggests, it is mounted on the Low
Voltage power line.
Powerline workers must meet both requirements listed below to be allowed to install
the equipment of the CURRENT 5000 and 6000 series:
1. Be qualified to perform work in the utility power zone (see OSHA 1910.269).
2. Receive appropriate CURRENT training specific to the CURRENT 5000 series
(training course CURRENT 5000 F101 – CURRENT 5000 Field Installation of
CURRENT Group equipment or the equivalent).

Installation
The steps for mounting the CT LVR on a utility pole are listed below.
Notes
Apply an approved lubricant (e.g., Burndy type A-13 Penetrox) to all
electrical connections.
When connecting the power cables of the CURRENT equipment, it is important
to remember that when only one of the red or black wires is connected, the
unconnected wire will float to the same voltage potential as the wire which is
connected. When both wires are connected, current flow is limited by the
circuitry in the equipment.
1. Ensure that the location where the CT LVR will be mounted is within six (6)
feet above the distribution secondary.
2. Screw a lag screw into the utility pole. Leave the screw protruding about 1/8
inch.
3. Hang the CT LVR on the protruding lag screw.
4. Ensure that the CT LVR is hanging vertically straight and install a second lag
screw at the bottom of the mount by tightening the second lag screw using a
wrench or bolt-driver against the bottom bolt connection of the mounting
bracket. Be sure not to bang so as to avoid any unnecessary vibrations of
the CT LVR!
When connecting the power cables of the CURRENT equipment, it is important
to remember that when only one of the red or black wires is connected, the
unconnected wire will float to the same voltage potential as the wire which is
connected. When both wires are connected, current flow is limited by the
circuitry in the equipment.
5. Cover the exposed wire on the red and black power wires with electrical
tape. This will protect in case of accidental contact with the power wires
before they are connected in step 10.
6. Cut ground wire to the length needed.
7. Attach one end of the wire to the CT LVR ground connector using a
screwdriver.
8. Attach the other end of the ground wire to the pole ground or neutral wire (if
there isn’t a pole ground) with a crimp.
9. Trim the CT LVR power wires to the shortest possible length that will still
reach the secondary.
10. Using either crimp type connectors or split bolts (whichever is the preferred
method of the utility) attach the unit wires using the following color code.
