50 amp Surge Guard Auto Transfer Switch | Southwire 41261-011 Exclusive Offer

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 V single-phase service typical in many 50-amp RV setups, making sure both legs of the supply are managed properly

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