Square D Electrical Panel & Breaker Service in Orange County
Square D is the panel we install most often in Orange County, and the QO line is the reason. QO breakers have the fastest trip response of any residential breaker on the market and a visible trip indicator that makes troubleshooting straightforward. Homeline is the value line and perfectly solid for standard residential service.
