Residential Electrical Load Calculator

You're planning a residential service and need to understand what the appliances add up to. Start with the connected ratings, then distinguish that total from the loads assumed to run at the same time.

This example contains 6 kW of general load, a 12 kW range, a 5 kW dryer, 4 kW of cooling and a 4.5 kW water heater: 31.5 kW connected. That sum does not select a service rating. This drawing compares illustrative operating schedules; an electrical design needs the applicable load-calculation method, nameplate data and installation conditions.
