Find appliance amperage charts online by visiting regional electric company websites or specific websites such as Do-it-yourself-help.com, Webb's RV Supply and Kamp of America. Most appliances have nameplates located on the back, side or bottom that include the amperage amounts.
Homeowners should determine appliance amperage before investing in a home generator or before upgrading existing electrical systems. This is to ensure that small and large appliances, lighting fixtures, televisions and other items receive the right amount of electrical current to run properly. For example, most small appliance circuits register between 15 to 20 amps, while large appliance circuits register between 20 to 60 amps. The number of appliances, along with the amperage, may determine the size generator needed to provide emergency electricity or the number of circuits needed in each room of the home.
