No, the GFCI part of the AFCI is not Class A GFCI protection. It has a higher trip level then a Class A GFCI.

But you could use an AFCI breaker supplying a GFCI device then onto the receptacles.
Thanks bob, yeah I knew that the trip level is much higher. The inspector was sure though that the AFCI breakers and GFCI outlets would conflict.

They won't as the technologies are completely different, with the exception of the GFE components of the AFCI breaker.

The only thing I can think of causing problems is a GFCI breaker and an AFCI something else. As I understand GFCI parts, there is a slight coupling between EGC and the other two conductors so any current flowing on the EGC can be measured. Thus, the AFCI downstream might cause enough current to flow for the more sensitive GFCI breaker to trip.

Disassemble a Leviton 7899-W GFCI and you will find no connection or coupling of the EGC terminal with the GFCI circuitry. Other models and manufacturers may be different.

FWIW, I have installed plenty of GFCI receptacles on AFCI protected circuits. There is no conflict, they operate together in peace and harmony.... :wink:

Not true, No egc is even required for them to function.

I just got off the phone speacking to an electrician about 2 wire receptacle repacements.He told me that he was going to replace 5, 2 wire receptacles with 5 GFCI receptacles, all on the same circuit.

I told him that was fine but I would also accept 1 GFCI receptacle and the other 4 receptacles could be 3 wire if he installed them in accordance with NEC 406.3(D)(3)(c)

He told me that another inspector told him that was no longer permited.

Am I missing something?

PS

There is no egc available.


I guess he was going to daisy-chain them as well, eh?:roll:

Well, if you go line-load on all 5 receps and A trips, than B,C,D, and E users are screwed regardless. My point was if he thought that they all needed to be GFCI's than maybe he knew not enough to not run them that way:rolleyes:

So you wouldn't use a GFCI breaker for any installation because of this? :rolleyes:
