Basement Outlets

Greetings,
On adding some outlets in a basement, Ive decided to pull another circuit -from new breaker in breaker box, through garage, to basement.
Will be using 1/2" flex couple of feet from box to garage wall, 1/2"emt to metal box in basement, then Romex inside basement along side other Romex to GFCI, then 2 other outlets.
Home Depot person said I could not run Romex inside conduit
(I will use 12 thhn solid for conduit run) as the Romex is conduit and you can't install conduit in conduit.
Any comments on this?
Seems to me I've seen pictures in electrical "how to" books showing Romex in conduit. Any other comments are appreciated.
Thank You, Randy

 

Have your local Home Depot electrician refer to the electric code article 334.15(B) which permits the cable to be run in conduit for physical protection.

 

Yes, but there are some benifits to running individual wires in the pipe though. For instance you could add one more wire and get twice the power or add another at anytime for switching.
