how much circuit breaker Measurement

This rating is labeled on the breaker itself. The standard for most household circuits are rated either 15 amps or 20 amps. An important note to remember is that circuit breakers can only handle about 80% of their overall amperage. That means a 15-amp circuit breaker can handle around 12-amps and a 20-amp circuit breaker can handle about 16 amps.

Then, multiply the amperage by 0.8 to find 80% of the rated amperage. For double-pole breakers, don’t add the amperage of the two breakers together because they will still operate on the individual amperage labeled on the handles.92%(40)

  • How to Calculate Electrical Circuit Load Capacity

    5 mins readBecause a homes main service is 240 volts, the math looks like this: 240 volts x 100 amps = 24,000 watts. 80 percent of 24,000 watts = 19,200 watts. In other words, a 100-amp electrical service should be expected to provide no more than 19,200 watts of power load at any given time.
