I ONLY do homes in EMT. If you would like to see any pictures of a home ruffed in EMT send me your email address and I will send them your way.

I would post them here but I dont have a clue how to do that.

Click here and scroll down to the second post for instructions on how to post pictures as attachments. If it doesn't make sense, scroll down more, that fellow needed more description to get it done too.

Try to post the actual picture (.jpg) as opposed to a compressed file (.zip or .sit), it gives the other person fewer steps to see the picture. :)

All receptacle circuits in the above calculations with one or more duplex receptacles would have to be sized at 15 amps. Rounding up to the next larger standard size for these circuits is not permitted.

How would you size it to 15A? You could put a gaziollion recepticals on a circuit via 220.3 (10) Or are you shooting for 240.4 B (1)?

I was using 240.4(B)(1). If the adjusted conductor ampacity is 18 amps and the circuit is feeding multioutlet receptacles (one or more duplex) then the rounding up to 20 amps is not permitted. So by loading the conduit with 28 CCC's and derating to 45%, a # 12 THHN conductor can not be protected 20 amps for these circuits.
 
Thank you Scott Moran for the pix

Nice professional looking job

This house is only about 80 miles from Chicago(I can tell you are from Chicago because of the horizontal receps)........maybe I should just have you rough it in:)........... I am sure my crew can handle it....just looks like alot of labor

I wondered about supports in your vertical runs 358.30(A)
 
Big Vic, the only time that any of the inspectors usally require vertical supports is if the conduit runs from the bottom plate through the top plate without hitting a box in between. While there may be other instances that technically should require it to be strapped, that is the general guidline here.
 
Here's Scott's pictures:

It was weird seeing the pipe running that close to the face of the studs in places.

Other than me being weirded out, very pretty work. It almost makes me want to move to Chicago and become a groupie :)
 
I haven't had a chance to look over the pictures yet (odd as that sounds) but I've noticed a lack of support for the conduit in the few I've seen. Were these taken prior to supporting them, or is this the final product?

If anyone has a particular picture they'd like to see full size, I can oblige. They were around 1.3+ MB per picture, so I downsized them so that I could upload them quicker. I'm on dial-up, so I looked to speed things up a bit. :)
 
NICE

I don't like the sideways mudrings...PITA to pull...but hey, when in Chicago :)

Those guys do so much pipe work they even had a bender named for them:

Chicago Bender ~

Applies to any mechanical bender .
 
Celtic,

Love that Greenlee!

Had a great time in Chicago back in the 80's(Alaska was bust, so they let us be "tramp" apprentices) during apprenticeship. Worked for Continental Electric and have to say it was one of the best places I've ever worked.

I noticed this as well. I saw virtually no supports. Does this AHJ consider a pipe coming through a drilled hole as supported? Around here, we end up installing hangar bars or 2x4's within 12" of boxes so we can install pipe straps or some other means of support.
 
I prefer to pull the wires after the drywall, prevents the wires from being cut by the drywallers rotozip. There are some towns that even require that you wait until after drywall however, I found only one town that requires you to pull before drywall. They wanted to check conduit and box fills so if they were too packed you could fix them.

You mean, plumbing-plumbing? Sure -- seen plenty. Just haven't seen a lot of EMT in my life that wasn't gunked up from being flooded or run by people as carefully as what I see here.

I'm a neat-freak when it comes to running Romex, in large part because I don't do it that much and find that it's easier for me to look around and figure where things go to and from. That pipe work was very easy on the eyes. The Romex Bob shared belongs in an art museum, not hidden behind sheetrock.

The first EMT work I ever messed with was in a large community center in the Upper 9th Ward. Much of our time was spent trying to decipher which piece of pipe went where -- plenty of diagonal runs all over the place, crossing over each other every which what way. My cohort in electron annoyance and I would climb into the attic, take covers off boxes, then fiddle with the wires to make sure we knew which box was actually connected to which other box. Then we'd mark the box cover with a Sharpie, one of us would climb down out of the attic, pull the flood wires out of the box that was below the flood line, and fish new wires back in. Had things been as orderly as the work I've seen here, I bet he and I could have spent a lot less time pulling on wires and going "Is this it?" "No" "Is this it?" "No" and more time fishing.
