The centerpiece of NSi’s incredible
product offering, Polaris in original
black is the insulated connector that
every other connector copies. Its
introduction marked the beginning
of a new age, providing the fastest,
safest, most professional connection
possible. In-line, wire entry from
either side, multi-cable, stacked – if
you have a need, there’s a Polaris
that works for you.
What’s better than the best insulated connector on the market?
The best insulated connector that
YOU configure, of course! Choose
your wire combination & quantity
of ports and we’ll custom engineer and fabricate your connector. Your custom connector will
even be UL rated! Whether Black,
Grey, or Blue, we’ll build the connector you specify based on your
project needs - and shipment is
made in only 3-4 days. Call us
at 800-321-5847 to discuss your
custom Polaris today.
Perfect for motors, Polaris Grey
provides the unique ability to connect or terminate fine stranded,
flexible, and ultra-flexible copper cable whenever maintenance
or repair are required. With an
integral sleeve that protects fine
strands and reduces stress on the
conductor, you can connect, disconnect, and reconnect with ease.
UL listed for use with fine stranded, flexible and ultra-flexible copper cables.
Finally, a Polaris for everything:
Polaris Blue is UL listed for direct
burial AND submersible applications. Its only limitation is the
cable’s limitation... so it goes
everywhere you need it to. And of
course, custom Polaris Blue is also
an option.
There simply isn’t an easier field
installation, where you can leave
your epoxies and heat shrink in
the truck!

THERE IS NO BETTER METHOD FOR MAKING A DIRECT BURIAL OR SUBMERSIBLE CONNECTION.
This UL listed connector will do for direct burial and submersible applications what the original Polaris did for your standard installations. Remember split bolts? Reduce your risk. No taping. No guessing. No cutting to size in the field. Leave your epoxies and heat
shrink in the truck! Polaris Blue provides an installation you can be sure of. Like all members in the Polaris family, Polaris Blue will
save you time and money, while guaranteeing a perfect connection every time.
FASTER:
Strip the cable. Insert into Polaris Blue. Tighten the screw. That’s it. Requires no taping, compounds, heat shrink, cutting,
or set-up time.
SIMPLER INSTALLATION: All you need is a knife and a slotted screwdriver or allen head wrench. You don’t need to
search for a propane torch, or find out who has the compression tool. You don’t need the skills of a surgeon to properly trim parts or
the training of a scientist to mix chemicals to complete a successful connection.
EASIER: Most repairs to a damaged USE or URD cable are found by using a post hole digger. Not enough space to ensure a
good connection when using traditional methods such as heat shrink or rubber kits. Unless you dig a giant hole (time is money...), it’s
pretty difficult to get a heat gun under the heat shrink. Plus, you have the investment in tarps, rain gear and cold medicine while you
wait for ideal conditions. None of this is a problem for Polaris Blue!
MORE RELIABLE: There is less chance for error since there is little work performed in the field. The installation has been
applied in a controlled, quality environment. Eliminates time consuming, expensive call backs.
BETTER: Insulated with specially formulated, high-strength dielectric plastisol and molded for a precise fit. UL486D rated for direct
burial, below grade use and submersible applications. Cold temperature rated to -45° C. Suitable for use with copper or aluminum
conductors and abrasion and chemical resistant. The connector is even supplied complete with oxide inhibitor.
COST EFFECTIVE: Polaris Blue is less expensive than traditional rubber or epoxy kits right off the shelf – not even including the
connector – and then add the cost of installation! The RS Means Electrical Cost Data calculates that 1 electrician splicing cable from #6
to #1 AWG requires 2 man-hours per splice and for cable from 1/0 to 250 MCM, approximately 2.5 hours. Including overhead and
profit, the cost of the smaller splice should cost $211. Polaris Blue can be installed in minutes, and the total cost of the connector is less
than the cost of an electrician for an hour. Easily the most cost-effective way to solve direct burial and submersible connection problems.

For display bags with a mounting hole for hanging, add the suffix “-B” to the part number.
Protect those fine-stranded wires with
Polaris Grey.
Here’s our secret: Polaris Grey comes with an integral sleeve
which protects the fine strands and helps the conductor maintain
its shape during the tightening process. The sleeve eliminates
breakage of the strands and reduces stress on the conductor and
therefore the potential for hot-spots. Replacement sleeves can be
purchased separately.
Specially designed for connecting and terminat-ing fine-stranded,
flexible copper conductors. Polaris Grey combines the reliability
and safety of a compression connection with the ease, affordability
and flexibility of a mechanical connection.
Motor replacement is now really easy. Simply strip the cable,
insert it into Polaris Grey, tighten the hex head screw, replace the
cap.

Polaris Connectors
CUSTOM-DESIGNED CONNECTOR BLOCKS
Let us custom engineer and fabricate a UL Listed insulated block system for your next project. Each connector
is made with exact hole size and number for the cable
runs being used. You may choose to order a customized version of our IPL Series or add one or more of the
options listed below. With the numerous configurations
and many options available, the combinations we can
create and produce are almost unlimited. Connector size
can be up to 22” long and is available with or without
insulation. Rated 600 V, 90°C.
We custom design a computer program from your
specifications and our engineering and production data
and put it in our computerized machining system. Your
blocks are then directly and precisely machined. We
then cover the block with our unique plastisol insulation
material/process. Shipment is made within 3 to 4 days!
Custom connectors are not returnable.
MOUNTING CAPABILITY
(Letter designation “M”)
Mounting holes can be added at each end of the connector block for situations where it must
be bolted in place. The mounting holes are provided in each end of the connector block and
are isolated from the block with insulated sleeves. When building a custom part number, add
the designation “M” to the prefix.
OFFSET WIRE ENTRY
(Letter designation “O”)
With this designation, the cable can enter either side of the connector block, based upon your
requirements. As shown here, the two primary cables enter from one direction, while the
secondary cables enter the opposite side from the opposite direction. This eliminates having to
bend the cable around the connector. Any combination of our eight basic sizes can be incorporated in these connectors. When building a custom part number, add the designation “O”
immediately prior to the ports that you want to enter from the opposite side.
STACKED WIRE HOLES
(Letter designation “S”)
Custom connector blocks can be supplied with one row of wire entry holes on top of the other.
This allows the block to be shorter in length and is ideal for use in small wire ways or panels.
When building a custom part number, add the designation “S” immediately prior to the ports
that you want stacked.
CUSTOM-DESIGNED POLARIS GREY
We can design a connector which will handle any combination and number of fine-stranded
wires between the sizes of 14 AWG and 3/0 AWG.
All wire ports can be on one side or opposing sides. The ports can be side by side, or
stacked on top of each other. Require mounting holes? Also no problem. Essentially, we can
do whatever you want, and ship it in three or four days! And best of all, your custom-designed
connector is UL Listed.

How to Build a Custom Catalog Number
Creating a custom catalog number may appear complex at first.
In fact, it’s quite simple, if you ask yourself the following questions and build your catalog number as you go.
1. Do you require an insulated block? If yes, start with the letter
“I”. If no, start with the letter “U”.
2. Do you require mounting capability? If yes, add the letter
“M”. If no, add nothing.
3. Now, you need to add the number of ports and size of wire
holes (using the letter designation for the wire size as listed
WIRE HOLE SIZES
below). You may add one size, i.e., 4F (4 ports of 500 MCM)
or many sizes, i.e., 4F6B2D (4 ports of 500 MCM, 6 ports of
1/0 and 2 ports of 250 MCM).
4. If you require any ports entering from the opposite direction,
group them at the end of the catalog number and use the
designation “O” immediately prior to the listing of these ports.
5. If you require any ports to be stacked, group them at the end
of the catalog number and use the designation “S” immediately prior to the listing of these ports.

Assembly of Connectors
Wire insulation must be stripped in accordance with the Strip
Chart below for Standard Connectors. The wire insulation on
a properly installed wire must be inside the insulated connector conductor port no less than 3/8 inch. Pressure screws must be
secured at the torque value corresponding to the wire size and
connector size shown to the right. The UL listing is for stranded
wire only. AL/CU 600 V max. for building wire and 1000 V
max. for signs or fixtures. When installing Mounting Connectors,
STRIP CHART FOR STANDARD CONNECTORS
use the Strip Chart below to select the appropriate mounting
bolt. Do not exceed 80 inch pounds.
When installing Custom Connectors, wire insulation must be
stripped such that when the wire is inserted into the conductor
port, there is a minimum of 1/4 inch insulation inside the conductor port. Insert the stripped wire until it stops against the back of
the connector.
