Square D Residential Enclosed Circuit Breakers are designed to be code compliant, easy to install, customizable and highly reliable. These rainproof Residential Enclosed Circuit Breakers are suitable for use only as service equipment since they feature a UL67 service entrance barrier, factory applied Emergency Disconnect and Service Entrance labels and the ability to select between factory installed molded circuit breakers (150 Amp to 200 Amp at the 25k AIR) or field installable molded circuit breakers (70 Amp to 200 Amp at the up to 100k AIR). Square D warrants its QO branch circuit breakers to be free from defects in material and workmanship under normal care and proper usage in a residential installation, for the lifetime of the load center in which it is installed.
