Blackburn IPC3541 TALON INSUL CONN 350-4/0 4/0-No10

The IPC3541 handles a main run of 350 kcmil down to 4/0, with taps from 4/0 down to No. 10. That range covers both the run and tap ports, so a feeder tap off 250 kcmil or 300 kcmil service conductors down to a #10 control or lighting conductor is within range. Sold each, so order one per splice.

No. The Talon IPC3541 is rated 300 V, so it is limited to circuits at or below that. For a 480Y/277 V or 600 V feeder tap you need a 600 V rated insulated tap connector or an uninsulated mechanical connector taped and insulated to the system voltage.

No separate taping or heat shrink is needed. The Talon IPC3541 is an insulated mechanical connector, so the insulating cover is part of the connector body rather than something you build up in the field. Set screw torque and conductor prep still apply as with any mechanical connector.

Yes. The IPC3541 carries a 90 degree C maximum temperature rating, which matches the 90 C insulation rating on THHN/THWN-2 building wire, so the connector is not the limiting element in the splice.

It carries UL file E9809. That is the reference an inspector or a spec reviewer will want, along with the 300 V and 90 degree C ratings.

A mechanical connector like the Talon IPC3541 tightens onto the conductor with set screws, so it installs with a hex key or torque wrench and no hydraulic crimper or die set. That makes it the practical choice for field taps and retrofit work in a gutter or panel where you cannot get a crimp tool onto the conductor. Compression connectors need the matching tool and die but give a permanent, non-adjustable joint. Within its 300 V and 90 degree C limits the IPC3541 does the same job with hand tools.

Black insulation on the body, and the connector is manufactured in Mexico. Useful if you are matching existing tap connectors in a gutter or documenting country of origin on a government or institutional purchase order.
