The Champion Power Equipment 201192 30 Amp Indoor-Rated Manual Transfer Switch with 25-Foot Generator Power Cord and Weather-Resistant Power Inlet Box is an easier, cost-effective way to manage a power outage. With 8 circuits available, the 30 Amp transfer switch is ideal for homeowners who want to power emergency essentials during a power outage, especially items without a cord like a furnace or air conditioner. Installing a transfer switch doesn't need to be complicated. The switch is prewired with labeled wires to make installation fast and easy. Need to replace or expand circuits. No problem. The circuit breakers are interchangeable. Use your included power cord to connect any 240-Volt portable generator (L14-30 receptacle required) to the power inlet box, even those with GFCI outlets. We recommend a Champion portable generator. The rocker switch on the front panel safely and easily transfers power to the selected circuits from either utility power or generator power. The power-indicating LED lights make it easy to determine where there is available power: utility, generator or both. A green light indicates utility as the power source at the transfer switch, blue indicates a generator power source and both lights illuminated means both sources are available.
