Winco 64488-000 30A Emergency Transfer Switch System
The ET/S System allows your portable generator to be quickly and safely connected to a building electrical panel for backup service during a power outage. A hinged lockable enclosure contains a 12-foot cord with a NEMA L14-30 twist-lock plug and stores the cord set when not in use. A quality Square D circuit breaker load center with interlocked generator and utility main breakers to prevent feedback to the utility, installs next to the building electrical service panel. Four 120-volt (or 8 tandem) or two 240-volt branch circuits or a combination of the two can be connected for emergency service. This manual transfer switch is not UL listed.
