More about the Pow-R-Line Xpert family

“I am always pricing jobs that require a specific main breaker, and Eaton's main breaker kits that bolt up universally into their panels is a huge selling point for me. The fact that a lot of Eaton's panel interiors are top- or bottom-fed is another great selling point.”
