Unless it's one of the AFCI brands that the GF portion was removed. GE and Eaton being a couple of them.

No it won't.

Pretty sure it won't. Not unless it is a combined AFCI GFCI. Might vary by brand and model.

Then niether would a continuity test.
Unless i missread where the fault is as you proposed?
With the afci open.. no. I guess i misread. Oops. I still got paid anyway...

Right the ones where the neutral doesn't land on the breaker no, but if the neutral goes through the breaker, a N-G will trip it. (Forgot about the no neutral ones, only come across those a couple times).

The combined AFCI GFCI are best referred to by their proper name Dual Function because the second generation of AFCI is properly known as a Combination breaker because it is supposed to be able to protect against parallel and series arcs.
Originally every manufacturer's straight AFCI breaker had ground fault protection in them at 30mA and all of them would trip on a neutral to ground fault. One of my troubleshooting steps when tracking down AFCI breaker problems was to swap the breaker with a straight GFCI breaker to eliminate wiring errors as a problem.
As Lil Bill mentioned two brands have the ground fault protection stripped out of them. That's ironic because the only addition to safety AFCI breakers ever added to a house was the ground fault portion.

The time it takes to test the circuits is, imo not worth it. When we used to use 1000' reels we ohmed it out before we pulled it. Probably not a bad idea but the only issues I had from the factory were very visible. I have installed many miles of nm cable and I have never had an issue with my wiring unless the siders put a 16 penny sized nail thru it.

The long nails used for foam popouts on the front of houses..
Ive also had the long lathe staples hit 'em too..

I don't believe that "having a neutral terminal on the breaker" = "performs some GF detection and will trip on a N-G fault". I recall one brand of single pole AFCIs advertising that you can use them on an MWBC, and just to land the neutral on one of the two units, doesn't matter which.

Fair enough. Perhaps I don't use those types or brands that have that (lack of) functionality. All I know is for me, a N-G fault pretty much always trips an AFCI breaker immediately.

My point is that the code requires wiring integrity. How do you do that? Some might think testing of some sort.

I am only pro-testing if not testing results in a failure and hurts someone.
For the work we do, we require insulation resistance testing per NETA ATS Section 7.3

So, what voltage are you going to megger at? Are you meggering before device installation, because most devices top out at 250 volts, and I don't know if meggering at that level tells you anything.

250 volt should be good for 120 volt circuits.
Most I've ever done was a continuity test at rough in.

I test the integrity of the wireing old coin test style. Take a good bite and make sure it's real good like checking gold coins for softness. If it tastes like romex and looks like romex then it better be. If it's not gritty enough then it needs more integrity

Certainly. To be most effective, other trades such as siding would be completed first. But of course no one is going to like more coordination and timing requirements.
