50 amp Surge Guard Auto Transfer Switch

Automatically transfers to generator power after about 30 seconds when it becomes available; when generator power stops, it reverts back to shore after approximately 3 seconds

Built-in multi-mode surge suppression protects against power spikes, open neutral conditions, reverse polarity, and other common faulty-park-power scenarios

Rated for 50 amp full load (FLA) contactors, mechanical interlocking, and UL 1008 full-transfer-switch listing (UL/CUL listed) — making it a robust choice for large RV/marine installations 

Designed for 120/240 volt single-phase service typical in many 50 amp RV setups, making sure both legs of the supply are managed properly

Hardwired installation in the RV’s main power bay or breaker panel location; clear instructions needed for mounting, wiring, and service access
