An electrical panelboard enclosure includes a primary service panel configured to receive power from a main power source and an alternate power source, an alternate power source connector array, and a distribution panel that delivers main or alternate power to subsidiary load circuits. A service transfer switch unit includes a main power breaker and an alternate power breaker having mutually interlocked toggle switches for respectively activating/deactivating the main and alternate power. The panelboard enclosure further includes a power cutoff switch operable from outside a service entrance door of the enclosure to mechanically engage and deactivate the main power breaker toggle switch.
