Briggs and Stratton offers a wide range of generators starting at 10kW up to commercial sized units. They run on either propane or natural gas. Standby generators are installed with an automatic transfer switch that detects when power is lost and starts the generator. Once the power comes back on the transfer switch transfers power back to the utility line and the generator is shut down. Generator sizing is based on your home size and electrical load such as heat and air units and appliances.
