I ordered a breaker that was a fraction of the price of a new one and it arrived in just a couple days time. It was a GE THQB, shunt trip, and initially I thought it didn't have the proprietary buss screws. No problem, I can use the ones I take out from the other breaker...When I went to install the breaker they fell out of the box....2 new screws. These guys will be my go-to supplier from this point forward. I service about 15 up-scale grocery stores and I'm constantly buying breakers.


Phenomenal service , the best company for electrical breakers. Simply breakers received my order, shiped the same night and the breakers arrived in under 4 days. I'll never shop anywhere else
