50A SURGE GUARD AUTOMATIC TRANSFER SWITCH

Automatically transfers to generator power after a 30-second delay when energized. If both shore and generator power are available, the generator takes priority after a 30-second delay. Shore power activates after a 3-second delay once the generator shuts down. Provides comprehensive electrical protection against faulty park power, including power surges, open ground/neutral, low (<102V) / high (>132V) voltage, reverse polarity, miswired pedestal, and high/low frequency. Features multi-mode surge suppression and RVC communications for real-time display of voltage, current, and fault conditions on an RVC-compatible device. Exclusive shore power sensing technology enables RVC network communication of both generator and shore power availability, allowing better control of the RV's power source and reconnection with available shore power. Front-panel indicator lights show L1 and L2 input power presence. Optional remote power monitor LCD Display (Part number 40299) sold separately.
