50 amp hardwire automatic transfer switch for RV shore power and generator power systems. Provides automatic source switching, generator priority, built-in electrical protection, multi-mode surge suppression, and RVC communication capability for compatible RV monitoring systems.
The Southwire 40450RVC3 is a 50 amp, 120/240V hardwire automatic transfer switch designed for RVs with both shore power and generator power sources. It automatically transfers power between the RV generator and shore power connection while helping protect the coach from unsafe incoming power conditions.
When generator power is energized, the transfer switch moves to generator mode after a 30-second delay. If both shore and generator power are available, generator power takes priority after the delay. When the generator shuts down, shore power is restored after a short delay.
Switches between shore power and generator power without manual cord swapping
Designed for 50 amp RV electrical systems using split-phase 120/240V service
Protects against common unsafe park power and generator power conditions
Supports RVC-compatible monitoring for voltage, current, and fault conditions
The 40450RVC3 is commonly used in motorhomes, fifth wheels, and other RVs with 50 amp shore power service and an onboard generator. It is useful when replacing a compatible 50A transfer switch or upgrading to a transfer switch with built-in Surge Guard protection and RVC communication capability. Verify the RV’s existing transfer switch wiring, generator output, shore power service, mounting space, and RVC monitoring compatibility before ordering.
• One Southwire 40450RVC3 50 amp automatic transfer switch • Hardwire enclosure with transfer switching and protection electronics • Installation documentation as supplied by manufacturer
This transfer switch is hardwired between the RV’s shore power input, onboard generator, and main electrical distribution system. It must be installed with the correct conductor size, torque settings, grounding, neutral routing, strain relief, and enclosure mounting. RVC communication features require compatible RV monitoring equipment and network wiring.
Transfer switch installation involves 120/240V AC power, high current wiring, shore power, generator power, neutral/ground bonding considerations, and RV electrical code requirements. Installation should be performed by a qualified RV technician or electrician familiar with 50 amp RV electrical systems. Disconnect all AC power sources and verify power is off before service.
