Abstract:
1. An electrical panelboard enclosure, comprising: an enclosure housing having an interior equipment chamber accessible via an opening in said housing; a service entrance door mounted on said housing and positionable between a closed position wherein said opening is covered and an open position wherein said opening is exposed; a service panel in said equipment chamber configured to receive main power from a main power source; a main power breaker in said equipment chamber having a main power breaker toggle operable to selectively activate and deactivate said main power, said main power breaker being positionable between a power-on state and a power-off state; a power cutoff switch mechanism operable from outside said service entrance door to mechanically engage and deactivate said main power breaker toggle and cutoff said main power without opening said service entrance door, said power cutoff switch mechanism being positionable between a power-on state and a power-off state; a lockout system comprising a first lockout component movably mounted on an inside of said service entrance door as part of said power cutoff switch mechanism, and a second lockout component movably mounted on said service panel to actuate said main power breaker toggle; said first lockout component being arranged to engage said second lockout component as said service entrance door is being closed; and said lockout system being operable to prevent said service entrance door from being secured in said closed position unless said main power breaker and said power cutoff switch mechanism are in the same state and said first lockout component is aligned with said second lockout component as said service entrance door is being closed, and if said main power breaker and said power cutoff switch mechanism are not in said same state as said service entrance door is being closed, said first lockout component will be in misalignment with and hit against said second lockout component such that said service entrance door will not be fully closable when said first lockout component hits against said second lockout component.
