HVAC marked circuit breakers - 09/19/02 10:20 PM
If a circuit breaker is used as an overcurrent protective device for air conditioning equipment must it be marked "HVAC"?
I've searched Article 240 and could not locate that as a requirement.
I found SWD and HID marked circuit breakers (NEC 240.83(D) but no requirement for HVAC.
