Can you place romex in EMT? Where in the code does it say you can or cant? I have asked this question to 3 electricians and got 3 different answers. Its a 40' run of 1/2"emt with 10/3 romex going into it. Thanks for any help.
99NEC Ch.9 Notes to Tables “A multiconductor cable of two or more conductors shall be treated as a single conductor for calculating percentage conduit fill area. For cables that have elliptical cross sections, the cross-sectional area calculation shall be based on using the major diameter of the ellipse as a circle diameter.”
Not sure if this would be the case for “Over 2 Wires: 40%” or “1 Wire: 53%” fill.
10/3 NM-B will probably need larger than ½-inch tubing.
for 10/3 romax cables(wires) you have to run it in 3/4 emt conduct. btw 1/2 inch conduct wont fit with 10/3 belive me it is a pain in the butt with that but i did check on nec 99 version it say same way check the area fill for conduct
merci marc
Pas de problme,il marche n'est-ce pas?"(No problem, it works doesn't it?)
Lighthouse, the answers were "yes you can", "no you cant", and "what the heck are you talking about". The 10/3 is running down the side of a house and I was going to place it in some EMT. I just wanted to make sure I wasnt breaking any code rules. Thanks for all the quick replys.
