I need an answer ASAP. Will Cuttler Hammer AFCI breakers interchange into a Murry panel? New construction. Thanks

Re: breaker interchange

Ryan,
It won't be listed for the application, but it may be classified for that use.

There is what I need to know. How do I determine out in the field if it is in fact classified for use?

Re: breaker interchange

UL requires that classified breakers be supplied with a listing of the panels that they are classified for use in. This most likely will not be on the breaker but on the box or 10 that they are shipped in. The following is from UL Guide DIXF (Circuit Breakers, Molded-case, Classified for Use in Specified Equipment).
The circuit breakers are Classified for use in specified panelboards in accordance with the details described on the circuit breaker or in the publication provided therewith.
