Derating output
WebJun 20, 2024 · A service panel for a typical modern house has a 200 amp busbar with a 200 amp main breaker protecting. We’ll use that as our example in the following calculation. For the 120% rule calculation, do the math to determine 120% of the busbar rating (which is just 1.2 x the busbar rating). Per our example, that would be 1.2 x 200 = 240 amps.
