Blackburn AMTD50048 AMT 8 PORT 500-4 DOUBLE SIDED CONN.

The AMTD50048 is an 8 port double sided multi-tap connector, so you get four ports on each side, eight conductor positions total. The port range is 500 kcmil down to 4 AWG, which is what the 500-4 in the model designation means. Ordered individually, one connector per unit.

It carries a 600 V rating, so it is suited to standard commercial and industrial power distribution up to 600 volts: service entrance taps, panelboard and switchgear feeders, motor control. It is UL listed under file E9809.

The body is aluminum. Aluminum-bodied mechanical taps of this style are the dual-rated AL9CU type used for both aluminum and copper conductors, but confirm the AL9CU marking stamped on the block itself for the specific run you receive before landing copper on it.

Double sided means conductors land on both faces of the block, four ports per side on the AMTD50048. That keeps incoming and outgoing runs separated on opposite sides, which is cleaner in a gutter or pull box where cables approach from two directions. A single sided block brings every conductor in from one face, which suits a wall-mounted enclosure where you only have access from the front.

This is a bare mechanical tap block, finished black, not a pre-insulated or fully enclosed device. Installed in an accessible enclosure, gutter, or pull box, it needs insulating cover or tape per your local inspection practice.

It is a power distribution tap: one or more large feeders land in the block and multiple smaller branch or tap conductors come off it, without splicing or a separate distribution panel. Common in service gutters, meter stacks, elevator and motor feeds, and retrofit work where you need to pull several loads off an existing feeder inside an accessible enclosure. Rated 600 V.

Country of origin on the AMTD50048 is the United States, which matters for federal, municipal, and institutional jobs carrying domestic preference language on electrical materials.
