Re: limit for using romex on apt building
1)Does the EMT go where you need the new circuit?
ANS. That's when it saves you time is when you can pull a new circuit to the area that you need it. When all the openings in the house are piped it's hard to imagine not being able to get close to where your going.
2)What product you are used to using?
ANS. I'm in an area that only uses metal conduit. I don't think that has alot to do with what I was trying to say.
It is hard to say you can run EMT to a new location faster than doing the same thing with cable.
ANS. It is probably easier to run new NM to a new location. Scratch probably and make that got to be unless it a relatively flat pipe run.
As far as the number of circuits possible that is still limited to a great extent by derating rules.
Ans. Four arc-faults = 1, 1/2"conduit, 6 kitchen circuits = 1, 1/2" but probably a 3/4" conduit, instead of multiple NM cables.
Still wounder how much the contractor saves the home owner/buyer per rough opening for NM instalations over EMT?
