Are you sure it is NM cable and not SE cable/conductors?Terminating 2 existing 3 wire NM cables in a newly installed residential sub panel. One for range one for clothes dryer.
I would say they should terminate on the neutral bar and not the equipment ground bar.
Is that correct.
Thanks
The 3 wire range and dryer circuits were only allowed to the main panel, not a sub-panel. If it's now a sub-panel they need to be upgraded to 4 wire.Terminating 2 existing 3 wire NM cables in a newly installed residential sub panel. One for range one for clothes dryer.

They were allowed if the grounded conductor was insulated. The grounding conductor in NM cable was never permitted to be used as a grounded conductor no matter where the circuit originated.The 3 wire range and dryer circuits were only allowed to the main panel, not a sub-panel.

I stand corrected. The range is SE cable.Are you sure it is NM cable and not SE cable/conductors?
As for the EM disconnect, you can label it "emergency disconnect, not service" and not have to run a 4-wire.
Panel needs to be 4 wire since I’m adding the Emergency Disconnect
Sounds like after 2026 NEC there must be a service disconnect on outside and run to the inside is always going to be considered a feeder. Basically no more "emergency disconnect-not service equipment".It can remain 3 wire after the Em Disco
If the NM cable has an insulated neutral than it's a 4 wire circurt and it's fine. If it's 10/2 or 8/2 w/ground, so two insulated hots and a bare ground, then it never met code.I stand corrected. The range is SE cable.
The dryer is NM cable.
Marked on the sheath as such.
Never met code, but certainly have seen more than enough.If the NM cable has an insulated neutral than it's a 4 wire circurt and it's fine. If it's 10/2 or 8/2 w/ground, so two insulated hots and a bare ground, then it never met code.
Yes, it was 10-3 w/o ground.Edit: Did they ever make NM cable with two hots a neutral and no ground? That would be OK as a three wire circuit for a dryer. I don't recall ever seeing that. That would be 10/3 or 8/3 without ground.
10-3, 8-3 and 6-3 (no ground) was very common before NEC started requiring separate EGC for all (new circuit) ranges and dryers.If the NM cable has an insulated neutral than it's a 4 wire circurt and it's fine. If it's 10/2 or 8/2 w/ground, so two insulated hots and a bare ground, then it never met code.
