Hello:

Regarding the use of EMT tubing in a residence.
Tried to find the answer to the following but couldn't.

Although it probably a lot harder to thread, was wondering if it Is code
permissible to run NM wire in EMT tubing, or must one use individual wires
(individual black, white, and a green Ground) ?

Is THW still the primary choice for residential usage in EMT tubing ?
Or,... ?

Thanks,
B.
