Branch Circuit Partial Run in Conduit

[Sjsmithjr]

For the life of me I can't fish the runs (NM) from a laundry room addition the last couple of feet back to the service panel. The service panel is mounted on an exterior wall. Is there a code compliant way come in the side of the box the last couple of feet via conduit? As I understand it 2x12-2 and 1x10-4 NM would violate the conduit fill rule. Is it permissible to strip the jacket once the NM enters the conduit?

Thanks.

Use larger conduit.

I'm guilty of not provided sufficient information again. I believe 2x12-2 and 1x10-4 NM would overfill 2-inch conduit, and 2-inch is the largest I can run.

Can't run NM on the outside no matter what kind or size pipe you install

Understood. I take it then the right way is to run NM to a junction box, then THHN from the box in conduit to the service panel?

Bummer of a week for the electrician in the family to be out of pocket...


Thanks,

Use type NM cable for the interior wiring to a "J box" and run conduit on the outside of the building with THWN or XHHW. The conductors must be suitable for a wet location.
