Question:
What is a HACR circuit breaker?
A
Answer:
UL indicates in their 1997 edition of the White Book (In my opinion, this is the rest of the Code book. I you don't have one, get one.) on page 22 that a HACR TYPE breaker marking indicates that the breaker is 'suitable for use with heating, air conditioning and refrigerating equipment marked for use with HACR Type circuit breaker.'
