Southwire Surge Guard 50-Amp Automatic Transfer Switch | Permanent Install, Shore Power/Generator

Motorized coaches that run on both shore power and a generator need a clean way to switch between the two without cross-connecting them. This Southwire (Technology Research) transfer switch installs permanently in the RV and manages that handoff automatically using mechanical interlocking contactors.

• Automatically switches between shore power and generator power
• Mechanical interlocking contactors prevent both sources from being connected at once
• 30-second delay before transferring to generator power once it's energized
• 3-4 second delay returning to shore power after the generator shuts down
• Rated for 50-amp, 120V service

Once wired in, it runs in the background, protecting your RV's electrical system from faulty park power and keeping the transition between power sources hands-off.
