BRSF125 Sub-Feed Lug Kit - Eaton Cutler Hammer 125 Amp 2-Pole for BR Load Centers

BRSF125 Sub-Feed Lug Kit - Eaton Cutler Hammer 125 Amp 2-Pole for BR Load Centers

Trying to figure out what a BRSF125 actually is? It is a lug kit, which is a set of connection points that go inside an Eaton BR load center. Wires attach to it, either as the main incoming connection or as a sub-feed heading out to another panel. What it does not do is protect the circuit, so this part is never a substitute for a breaker.

The rating is 125 amps across two poles. Wire from #8 up to 2/0 AWG connects to it, in copper or aluminum. Fitting it into a panel uses two of the 1 inch slots. Eaton lists the part as UL Listed.

Common Applications

• Connecting a sub-feed that leaves a BR load center for another panel
• Serving as the main wire connection inside a BR load center
• Adding a connection point to a panel that is already installed

FAQ

How much panel space is needed? Two of the 1 inch slots.

Which load centers is it made for? Eaton publishes it for Type BR load centers.
