What to do with unneeded NM conductors?
@Megawatt Yes, actually I'm using AFCI/GFCI outlets. That occurred to me but I figured that removing the protective sheathing would violate code.- Noah Katz

What to do with unneeded NM conductors?
I'm updating my kitchen wiring and I believe the in-ceiling ventilation fan needs to be AFCI-protected. To accomplish this electrically all I need to do is pigtail into the hot wire of one of outlets on the load side of the AFCI outlet. Can I just clip off the unused neutral and ground wires...- Noah Katz

Correct grounding of metal junction box w/splices for 3 circuits
@davesparks Solid points, thanks very much for taking the time to explain. @Cookie Hmm, yes it will if it gets disconnected at the ground end; another good point, thanks. -

Correct grounding of metal junction box w/splices for 3 circuits
Hmm, I didn't get a reply notification; anyway How could a neutral be anything but dead when it's grounded at the panel? Regardless, the crux of the matter which no one has addressed, is how it can make any difference if the neutrals are tied together at a junction box when they're already... -

Correct grounding of metal junction box w/splices for 3 circuits
I'm not talking grounds vs. neutrals. Two people said there was a hazard in connecting the neutrals from different circuits together. They're already connected together at the panel neutral bar, so how is the hazard created? -

Correct grounding of metal junction box w/splices for 3 circuits
After further thought, I realize I really don't see the hazard in pigtailing all of the neutrals together, since they're all connected together at the neutral bus bar in the panel. What am I missing? -

Correct grounding of metal junction box w/splices for 3 circuits
I guess that is a bit ambiguous. These are three separate circuits as required by 2020 NEC, each on it's own breaker, black/white/green THHN runs for each. I'll keep the different circuits' neutrals isolated, and thanks westward10 and Dave for pointing out the hazard of doing otherwise. -

Correct grounding of metal junction box w/splices for 3 circuits
Cool, thanks. Another question that I realize I need an answer to - should I pigtail all of the neutrals together? I have a feeling NEC says no, but on the plus side, the extra copper would reduce voltage drop when less than full load capacity is being utilized, and it would be a wash if all... -

Correct grounding of metal junction box w/splices for 3 circuits
I have 3 circuits (microwave, disposal, and dishwasher) entering a metal box where the THHN wire will be spliced to Romex. I spent half an hour reading 2020 NEC Article 250 but didn't see multiple circuits specifically addressed. To ground the box do I just need to pigtail off of one circuit's...
