Enter the voltage of the outlet, breaker amps, and power usage (watts) into the calculator. The calculator will evaluate and display the percent load.

The following equation can be used to calculate the percentage load on a circuit breaker.

L = P / V*A *100
• Where L is the % load
• V is the voltage
• A is the amps
• P is the current power usage

To calculate an electricity load percentage, divide the power usage by the product of the voltage and current, then multiply by 100.

An electricity load is a measure of the total percentage of available load that an application is using up.

1. First, determine the power

Determine the total amount of power being drawn from the outlet.

2. Next, determine the volts and amps of the outlet.

This will be the standard voltage and amps the outlet produces.
