Nm in pipe

If someone were to stick a 10/2 wg romex or nm-b cable in a pipe how big should the pipe be? Would 3/4 fly??? EMT

NM should not be used in conduit unless it is just being sleeved.

As far as I know, there are no NEC restrictions against NM in conduit. In fact, the NEC refers to it many times, and even tells you how to compute the conduit fill for complete conduit systems containing cable.

I have heard of local restrictions on NM in conduit, so it's wise to check locally.

Measure the width of the 10/2 NM at its widest (I don't have any handy). Post back and we can compute the required EMT size.

Sperry27, If its just one 10/2 cable 3/4" should be ok. If 1/2" is too small for 12/2 you know its too small for 10/2. I've never had a problem with an inspector here in the Detroit area using 10/2 or 10/3 in 3/4" for an electric dryer circuit.
