Understanding Circuit Breaker Ratings and Its Specification

WebEvery circuit breaker has a specified amperage (amount of current). 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. WebApr 2, 2024 · Then, multiply the result by 125% (sizing for overcurrent protective devices — OCPDs — when continuous loads are involved). Ideally, the rating of your circuit breaker should surpass the total power of this equation. Step 3. Calculate safe circuit load. The operation of a circuit breaker should only occupy 80% of its capacity. darlene kawano clovis california https://infotecnicanet.com
