Installation Overview: The NEW Square D 300A/400A CSED | CED Antioch

Smarter installs start here. Square D QO and Homeline 300A/400A CSEDs combine the meter socket and outdoor disconnect into a single, compact, lightweight enclosure, designed for plug-on neutral circuit breakers. Each enclosure features an integrated load center, offering flexible options to stay compliant with evolving code requirements (AFCI, GFCI, and surge protection). Add a Schneider Energy Monitor to help homeowners track their energy usage and save money. Further enhance QO CSEDs with Square D control relays for circuit-level control. Built with future-ready flexibility, these CSEDs support alternate power sources such as solar, generators, and battery storage.
