Circuit breaker rated 100%
WebJun 18, 2024 · 100% breakers are essentially the same as 80% breakers but can deal with the additional heat the thermal element generates when running at 100% for extended periods of time. Not really an issue with electronic trip elements since they have no heater. WebSep 24, 2024 · Sep 23, 2024. #2. As I understand it, the issue is that a thermal magnetic circuit breaker will not reliably hold 100% of it rated current continuously. It has a good chance of tripping under those conditions. As a result, various NEC rules limit the continuous current allowed on the breaker to 80% of its rating.
