Leviton circuit breakers provide overload and short circuit protection, and feature a universal connection design. All live and neutral wires have terminations across the panel, not the circuit breaker, so the entire panel can be wired to infrastructure without circuit breakers installed. The branch circuit breakers are easily pluggable in the final installation. The circuit breakers also have color indicators in the handle that allow you to see the operating status at a glance. This breaker will work only in Leviton branded residential panels.
