Leviton is proud to bring the Load Center into the 21st century with a focus on improved safety and ease of installation. Thanks to its revolutionary design, all hot and neutral wires terminate at custom lugs in the panel, rather than at the circuit breaker*, which allows the entire panel to be wired at rough-in. Branch circuit breakers are simply plugged-in at final installation, increasing jobsite efficiency. Leviton Dual Function branch circuit breakers feature an intuitive color indicator in the handle, which designates operational status at-a-glance, as well as a line-side powered LED to indicate when a fault has occured, and what type of fault - arc, or ground.
