Two-port insulated multitap

The Polaris nsi IT-250B is a two-side insulated multitap connector designed for electrical installations joining aluminum or copper conductors. It accepts stranded copper wire sizes from 6 AWG up to 250 kcmil. The body is aluminum with a black plastisol finish providing insulation. It is cULus listed to UL 486B and RoHS compliant.

Thermals and power rating

The connector carries a maximum voltage rating of 600 V and a maximum operating temperature of 194 degrees F. The plastisol insulation material has no UL 94 flammability rating applicable. These ratings define the safe thermal and electrical envelope for continuous use in approved circuits.

Hex drive and compliance

Each port uses a hex head style with a 5/16 in hex size for secure tightening. The two-port layout measures 2.13 in length and 2.31 in width. RoHS compliance and cULus certification to UL 486B confirm the connector meets recognized safety and environmental standards for industrial wiring.

Questions about this item

How do I install the Polaris nsi IT-250B using the 5/16 in hex head?

Strip each conductor to the correct length, insert the stranded copper or aluminum wire into both ports, then tighten the hex screws with a 5/16 in driver until secure. The step often missed is verifying full wire insertion before final torque.

What maintenance or replacement will the Plastisol insulation need over time?

Inspect the black Plastisol coating periodically for cracks, hardening or discoloration caused by heat cycles up to 194 Degrees F. Replace the connector if the insulation shows any degradation that could expose live metal.

At what sustained load does the 600 V rating become the limiting factor?

The connector is rated for a maximum of 600 V. Under continuous operation, voltage drop across the aluminum body and contact resistance will reach the 600 V design limit before the 194 Degrees F temperature ceiling becomes critical.
