What wire sizes do the terminals on the CH2150X accept?

The box lugs accommodate copper or aluminum conductors ranging from 14 AWG up to 1/0 AWG.

    Got a great refurbished breaker - saved a $6500 Service Replacement

    When our main breaker frizzed out, the option we were presented with was replacing the entire panel and service due to the type and part - no longer produced for replacement parts. It would be a $6500 replacement.

    We'll likely have to do it at some point but, for now, the replacement breaker we were able to source from Superbreakers (with a $25 warranty) was $5900 less expensive. installation ran a few hundred dollars and the tech said the part looked to be in excellent condition and was prepped for install as he would have hoped.

    Very thankful for SuperBreakers!
