#21784 - 02/10/03 07:29 PM Romex in EMT  

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.

wildturkey :

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

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.

Is this running down the inside or outside of the house?
