Four-Port Insulated Multitap Connector

The Polaris IPLD350-4B is a four-port insulated multitap connector designed for joining aluminum or copper conductors in electrical installations. Its plastisol-insulated aluminum body accepts stranded copper wire from 6 AWG up to 350 kcmil per port. Rated for 600 V and a maximum operating temperature of 194 degrees F, it suits industrial and automotive wiring tasks where multiple cables must terminate at a single point.

Sustained Load Behaviour

The connector carries continuous current at its rated 600 V and up to 194 degrees F without degradation of the plastisol insulation. Hex-head set screws tightened with a 5/16 inch driver maintain consistent clamping force on each conductor, preventing resistance rise during prolonged operation. The aluminum body dissipates heat across all four ports, supporting stable performance in enclosed raceways or junction boxes under full rated load.

Pre-Installation Checks

Verify that each conductor falls within the 6 AWG to 350 kcmil stranded copper range and that the insulation material is compatible with plastisol. Confirm the available space accommodates the 4.57 inch overall length and that the 5/16 inch hex tool can reach each set screw after cables are dressed. Ensure the installation complies with UL 486A and cULus requirements for the intended circuit voltage and environment.

Questions about this item

How warm does the connector get when it runs at its 194 °F rating all day?

The connector is rated for a maximum operating temperature of 194 °F, so it will not exceed that value under normal continuous load.

What wire sizes and tools do I need to install this four-port multitap?

It accepts stranded copper from 6 AWG up to 350 kcmil and uses a 5/16 in hex head for tightening.

Will this Plastisol-insulated aluminum body work safely with my older 600 V copper feeders?

Yes, the connector is rated for 600 V and listed for both aluminum and copper conductors under cULus and UL 486A.
