How to Calculate Circuit Load
What is Circuit Load?
An electrical circuit load calculator determines whether a circuit can safely handle the added electrical demand of new appliances or fixtures. A 15-amp circuit at 120V delivers 1,800W; keep total load below 80% (1,440W) for continuous operation. Exceeding circuit capacity trips breakers and creates fire risk.
