Home generators are an investment, but they offer increased power capacity and are ready to go when the power cuts out. They generally range from 7 kW to 22 kW of power or more when installed for home use. To keep important appliances like your refrigerator or your air conditioning running, home generators generally rely on either a natural gas or propane connection. Alternatively, you can shop for diesel-fuelled home generators, but be aware that additional codes may govern the installation of this type of home generator.

Home generators vary in wattage and you should factor in both starting watts and running watts for your home’s power supply needs. Standby generators should always be installed with a transfer switch to prevent back-feed that can cause harm to your home’s electrical system, the generator, or serious injury and death to utility workers.
