StormSwitch ready-to-install commercial manual transfer switches are designed to provide safe, portable generator hook-up to a building when utility power is out. According to the company, integral utility and generator manual disconnects are interlocked to prevent cross connecting the power sources. The disconnects can be supplied as either molded case circuit breakers or switches. UL-listed, the units feature a safety-interlocked door and dead-front panel.
