摘要: An electrical panelboard enclosure includes an housing with interior equipment chamber accessible by way of a service entrance door. A panel is configured to receive power from main source. breaker has toggle switch and positionable between power-on state power-off selectively activate deactivate the power. cutoff mechanism operable outside door mechanically engage without opening lockout system prevent being secured in closed position unless are same state.
