Southwire 50A Basic Automatic Transfer Switch Hardwire Model

This 50 Amp automatic transfer switch has mechanical interlocking contactors, a time delay at power up, and dual contactor arrangement.

It transfers to generator power automatically when energized after a 30 second delay. When both shore power and generator power are available, the generator dominates after a 30 second delay. Once the generator is shut down, shower power activates after a 3-4 second delay.
