Thank you for this page.
It brings a lot of code knowledge and the answers are very comprehensive. This what I encounter on my prints: "HACR breaker are to be used where call out on equipment nameplate". It's my first time that I read about HACR breakers. Does the NEC refers to that type of breaker? My main question will be, What is a HACR circuit breaker?
The term HACR breaker means that the breaker is "Heating and Air Conditioning Rated (HACR). Our sources indicated that circuit breakers listed to UL 489 are HACR rated.
