It's not as bad as it sounds, the longest single run of 4/0-4 that I was personally involved with was about 250' but it had to be pulled above a suspended ceiling .... and the cable can't drag on the ceiling or it will mess it up. We went along and hung a series of pulleys, pulled the cable then went back to support and remove the pulleys. Pretty much like how the utilities string cable on poles.
It's all in what your used to.
We still do run pipe for some things, but cable of any type is used a lot here in this area.

Its very rare here in larger sizes. I cant say that I have ever seen MC cable in size 4/0. #10 is the largest we can get off the shelf.iwire said:

We looked into using some 500 Kcmil - 4 MC for an installation but it would have been parallels and you run into EGC issues. (250.122(F)) I ended up running 5 - 3" EMTs instead.
Not to say that a well done pipe job does not look good, like Eric's here in this thread.

"Check out the T.W.I.N.K.I.E.S. Electrical Resistivity Project. "
Sparky, what a horrible test, a multimeter? What did they expect, I will redo this test someday with a 5kV megger and a 50kV hipot and post the results, I have not had a twinkie in my possesion in about 20 years, might be worth a stop and the quick-E-mart.

I just cant believe that could ever be cheaper than pipe and wire at that size.
Anybody have labor units on 500 mcm Al MC vs EMT and Al wire?
200' run
2- 90s and two junction boxes
Assuming a high ceiling like the Walmart job?

Thats what I'm thinking... or have always been thinking. I personally haven't seen any MC past 10-3. Some of those large sizes sound like back problems.

Believe it, assuming you used to, and equipped to install it.
I can have that whole run installed before the 50% of the EMT is in place and then you still have to pull the conductors and terminate them.
It's not even close.
FWIW, when we looked into using 500-4 copper MC it was about $39.00 per ft, which was not much more then just the XHHW we ended up using.
But hey...I still think Eric's job looks better.

No, but if you lived in this area you would not use them nearly as often as you would on many big jobs as you would in other parts of the country.
MC cable is king here. A lot of it has to do with a major MC manufacturer located nearby and we have immediate access to many different sizes and types of cable. And it's also how we do jobs here - get them done fast and move on to the next.

weve ran 4/0-4 MC before. we needed 2 runs and each run was about 300'. it wasnt that hard at all to do. just need a few extra people to help pull it and feed it. not hard at all.

Impossible to install pipe with 360 deg or less, and didn't want to/couldn't put large J-boxes in the drywall ceilings.
It wasn't a question of cost, there were far too many obstructions for conduit. MC was the way to go.

Wasnt asking about a specific job just wanted to know if anybody had labor units handy for the type of installation I described.

Granted, the main reason why I have all that pipe there now that I think about it a little bit more... I was there pretty damn early, and most of the other trades were on other jobs at the time I showed up. I knew where people were going to be "In my way", so I purposly ran things where I knew I could claim my real estate so to speak.
Wal Mart spec'd pipe for almost everything, and in talking with people around here, they've heard of larger MC, but almost NONE goes out of the supply houses in town that I talk to. All-Phase, Wabash, Grainer, Graybar... Maybe its just too heavy, and their just too lazy.. lol I don't know
I want to see some now.. What kinda straps are those? Sure in the hell can't be 1 hole straps.. lol Unless you're using a 1/2" bolt.. :roll: :wink:

If you have some pics of big MC installed or even on a roll I would like to see it. For some reason its not used in south florida. Possibly due to the fact that we have very little industrial work.

Here is a picture of 6 runs of 500/4 shielded MV, we had installed the 4 runs on the right not long before the picture was taken, I believe these were 600 to 700 feet long. There are runs over 2000 feet long on this site.
It takes serious rigging and equipment for these installations, the reels come by rail into this mill and are unloaded and set up with cranes. The wire reels are fabricated on site with I-Beams.
I think it weighs 12 + lbs per foot.

Looks like you may be the guy that started wiring with romex and then learned pipe. Is this your work? :grin:
