  • Accepts 14 AWG to 2/0 AWG line conductors
  • Six load connections per pole support multiple branches

Two-Pole 175 A Distribution Block

The Bussmann 16321-2 is a two-pole copper power distribution block rated for 175 A at 600 V. It suits panel builders and electricians who need to split a single feed into multiple branch circuits inside a control cabinet or equipment enclosure.

Line 2/0 AWG to Load 4 AWG Capacity

Each pole accepts one line conductor from 14 AWG up to 2/0 AWG and distributes it to six load terminals that take 14 AWG to 4 AWG copper wire. The 175 A copper rating provides headroom for substantial loads, while the 600 V maximum covers common industrial control voltages.

Replaces Single-Terminal Blocks or Bus Bars

This block replaces individual terminal blocks or simple bus bars when a compact, surface-mount solution with multiple load connections per pole is required. The jump is worthwhile when wiring density demands six load take-offs per phase and a 175 A copper rating meets the circuit design.

Questions about this item

Will the 175 A copper rating handle the existing 2/0 AWG feed cables in my panel?

Yes, the line side accepts copper from 14 AWG up to 2/0 AWG at 175 A and 600 V, so your 2/0 AWG feed cables are within the specified range.

How can I verify the block is carrying load correctly after wiring?

With power on, measure voltage across each pole at the load terminals; a reading close to your supply voltage and stable temperature at the 14 AWG to 4 AWG load connections confirms proper operation.

Does the 16321-2 include mounting hardware or terminal screws for the six load connections per pole?

The block provides the 2-pole copper bus with one line and six load openings per pole; mounting hardware and any additional terminal screws are not included and must be sourced separately.
