NSi IPL Polaris™ Insulated Multi-Tap Connector, Single-Sided Entry

The NSi IPL Polaris™ Insulated Multi-Tap Connector family delivers secure, code-compliant wire termination for commercial and industrial electrical work, available in a range of single-sided entry (SSE) configurations from 3-port to 5-port with wire ranges spanning 4-14 AWG up to 1/0-14 AWG conductors depending on the configuration selected. Every connector in the IPL Series shares a durable black Plastisol insulating housing and finish, is rated 600V and 90° C, and is engineered for Class B & C wire types, giving installers a dependable insulated tap point for multiple conductors landed from a single side of the connector body. Listed cULus, these connectors provide a reliable, professional-grade connection point wherever consistent multi-tap performance is required.

Key Features

  • Wire Range: Configurations accept conductors from 4-14 AWG up to 1/0-14 AWG, providing flexibility to match the connector to the application's conductor sizes.
  • Port Configuration: Available in 3, 4, and 5-port Single-Sided Entry (SSE) designs, letting installers land multiple taps from one insulated connector body.
  • Durable Insulation: Black Plastisol material and finish form an abrasion-resistant insulated housing that protects the termination point in the field.
  • Electrical Rating: Rated 600V and 90° C across the family, suited for demanding wire termination applications in commercial and industrial settings.
  • Wire Type Compatibility: Engineered for Class B & C wire types, supporting common stranded and solid conductor constructions.
  • Single-Sided Entry Design: Simplifies installation by allowing all conductors to be inserted from the same side of the connector body, streamlining multi-conductor terminations.
  • Application: Purpose-built for wire termination tasks in panelboards, distribution equipment, and service entrance assemblies.

NSi IPL4-3 – Frequently Asked Questions

1) What wire sizes will the NSi IPL Polaris multi-tap connector accept?
The IPL Polaris insulated multi-tap connectors cover 4-14 AWG up to 1/0-14 AWG depending on which configuration you order. The IPL1/0 versions take conductors from 1/0 down to 14 AWG in any port, so a single connector can land a 1/0 feeder and smaller branch taps together. The IPL4-3 is the smaller range, 4-14 AWG, 3 port. Match the connector to the largest conductor you need to land, since the port will not take anything above its top size.
2) How many taps can I land on one Polaris IPL connector?
Three, four, or five ports, all single-sided entry. The 1/0-14 AWG range is offered as IPL1/0-3, IPL1/0-4 and IPL1/0-5; the 4-14 AWG range comes as the 3-port IPL4-3. Count your feeder plus every tap conductor and pick the port count to match, because every conductor occupies its own port.
3) Can I use the NSi IPL connector on 600V service entrance and panel wiring?
Rated 600V at 90 degrees C, and cULus listed, so it is suited to panelboards, distribution gear and service entrance terminations. The 90 C rating means it will not be the limiting element where you are terminating 90 C insulated conductors such as THHN.
4) Which NSi IPL part number do I order for a 1/0 feeder with four branch taps?
That is five conductors total, so the IPL1/0-5, the 5-port version of the 1/0-14 AWG range. If the taps total three, use IPL1/0-4; two taps, IPL1/0-3. All three accept anything from 1/0 down to 14 AWG in each port.
5) What is the difference between the NSi IPL Polaris multi-tap connector and a Burndy UNITAP connector?
The NSi IPL Polaris is an insulated multi-tap connector with a single-sided entry configuration, so every conductor lands from the same face of the connector body, and it carries a black Plastisol insulating housing rated 600V and 90 C, cULus listed, for Class B and C conductors. The Burndy UNITAP is an aluminum multi-tap connector built as a run/tap device, meaning the run conductor passes through and taps are made off it. Choose the IPL Polaris when all conductors are being landed from one side as taps; choose a run/tap style body when a continuous run conductor has to pass through the connector.
6) I need a multi-tap connector where the main run conductor continues through the device - will the NSi IPL Polaris work?
The NSi IPL Polaris is a single-sided entry device, so all conductors enter from one side and terminate inside the connector body rather than passing through it. For an application where a run conductor must continue through the connector with taps made off it, a run/tap style body such as the Burndy UNITAP is the configuration that matches. The IPL Polaris is the right choice for landing multiple taps at one insulated point from a single side.
7) What does single-sided entry mean on a multi-tap connector, and when would I want double-sided instead?
Single-sided entry means every conductor, feeder and taps alike, enters from the same face of the connector body. That suits a panelboard or gutter where all your wire comes from one direction and you want the shortest, tidiest terminations. A dual or double-sided connector is the one to use when the feeder comes in one end and the taps leave the other, like a run-through splice in a wireway. The NSi IPL series is the single-sided configuration.
8) Will the Polaris IPL work with solid wire or only stranded?
It is built for Class B and C stranded conductors, which covers the common building wire and cable constructions you will meet in commercial work. Fine-stranded welding or DLO cable is a different class and is not what this connector is specified for.
9) Does the NSi IPL connector need to be taped or boxed after I make the connection?
No separate insulation is needed on the connector body itself. The housing is black Plastisol, an abrasion-resistant insulated cover over the termination, so the tap point is insulated as supplied. You still have to land it inside enclosure and code requirements for the installation.
10) Do I need to add insulating tape or a cover to a Polaris IPL multi-tap connector the way I would with a bare aluminum connector?
No. The NSi IPL Polaris ships with a black Plastisol insulating housing as part of the connector, rated 600V and 90 C and cULus listed, so the termination point is insulated as supplied. A bare aluminum multi-tap connector such as the Burndy UNITAP is an uninsulated body, so insulation of the finished splice is handled separately in the field. If you want the insulation built in, the IPL Polaris is the one to specify.
11) Which multi-tap connector should I use for 1/0 AWG feeders with three to five taps in a panelboard?
The NSi IPL Polaris covers that directly: it is offered in 1/0-14 AWG with 3-port, 4-port, and 5-port single-sided entry bodies (IPL1/0-3, IPL1/0-4, and IPL1/0-5), all rated 600V and 90 C and cULus listed for Class B and C conductors. A smaller 4-14 AWG 3-port version, IPL4-3, handles lighter branch-circuit taps. If the design instead calls for an aluminum run/tap body, the Burndy UNITAP series is the alternative construction.
