Product Details

The transfer switch monitors utility power and signals the generator to start when utility power is interrupted. When utility power returns, the transfer switch returns the electrical load from the generator back to the utility. This ensures your most important electrical loads are powered, within seconds, even when you’re away. All RTS transfer switches are housed in a NEMA/UL Type 3R enclosure, with electrostatically applied and baked powder paint.
