Check how loaded a branch circuit is from its outlets.
Multiplying the outlets by their expected wattage gives the total load, converted to amps and compared to the breaker rating as a percentage. A circuit is meant to run comfortably below its breaker rating, so checking the percentage protects against tripping and overload.
Circuit Load
Load % = (outlets x watts / voltage) / breaker rating x 100
Load % = (outlets x watts / voltage) / breaker rating x 100 Multiplying the outlets by their expected wattage gives the total load, converted to amps and compared to the breaker rating as a percentage.

This calculator takes 4 inputs: Breaker rating, Voltage, Outlets, Watts per outlet. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
