I don't like the tone of that statement. I agree that it is important to take pride in your work; however, just because an MC or AC job doesn't look as pretty as and EMT or IMC job doesn't make it bad.

If the job is safe and serviceable, what is really wrong with it and how much are you willing to pay just to have it look pretty? After the drywall is installed, which one will look the best?

It should be second nature to install your work in a manner that makes it look good,if no other reason than it is easier to come in later and add things if the original installation was properly done with conduit (or mc,whatever) are straight or plumb.

Not to take your remark out of context,I have fired people for telling me no one would see it after the sheetrock was hung.Most people I have worked with over the years indicated that they felt the same way.

Every employer has a right to set the standards of workmanship for his/her employees to follow. I don't object to having something done that exceeds minimum requirements, but I also have come to accept those times when the bare minimum is done. Its just the way it is these days, and there is not a lot you can really do about it.

I for one could care less if someone runs Romex, EMT, or some other cabling method and then hides it behind drywall. As long as its safe and functional, its Ok by me, even if it might not be perfect by other standards.

OTOH, I want exposed work to look like it was done by a professional.

One of the points I was trying to make above is the installer who does the 'professional' exposed conduit job more than likely runs mc and romex in a manner that is pleasing to the eye as well.I think we're all on the same page here. :)

Re: M C CABLE BUNDLING

In reference to your example of 20 bundled MC cables. If your current carry conductor count does exceed 20 and you have to apply the 60% derating factor, I remind you why the 60% adjustment was taken out of out what now is 310.15(B)(2)9(a).

Assuming 90 degree C conductors, the new ampacity would be 18 amps (30 x 60%) If you are supplying loads that are covered by 240.4(B)(1)you have to provide 15 amp OCPD or use #10 wire.

Also note that that the exception for MC does not apply to #10 conductors.
