Blackburn AMTD4144 AMT 4 PORT No4-14 DOUBLE SIDED CONN

The AMTD4144 is built for conductors from #4 through #14 AWG, which covers typical branch circuit and feeder tap work in that range. It has four ports, split as a double sided connector, so conductors land on both sides of the body.

Yes, the connector carries a 600 V rating, so it is suitable for standard commercial and industrial 120/208, 240, 277 and 480 V systems inside enclosures and gutters. It is UL listed under file E9809.

The body is aluminum, which is the standard construction for dual rated AL/CU mechanical tap connectors. Check the AL9CU or AL/CU marking stamped on the part itself for the conductor rating before terminating, since that marking is what an inspector reads.

Double sided means the four ports are divided so conductors enter from two opposite faces rather than all from one end. That is the layout you want when the main and the taps come into the box from opposite directions, or when you need to keep conductor bends short in a tight gutter. A single sided block is easier when everything feeds in from one side.

This is a bare mechanical tap connector, not a pre insulated device, so it has to be installed inside an enclosure, gutter or pull box, or covered with an appropriate insulating cover or tape per the installation requirements. Its color is black.

It is sold each, so quantity ordered equals connectors received. For MRO stocking, order one per tap point rather than per conductor, since a single AMTD4144 handles four conductors across its four ports.

Country of origin is Mexico. That matters if you are bidding work with domestic sourcing or origin documentation requirements, so confirm the spec on the job before you submit it.
