I will have around 700 feet of two conductors of 4/0 with one conductor of
3/0 or 2/0.

This is called triplex and is for underground and rated for 200 amps.

It is aluminum; who can afford copper?

It may be around 2.25 per foot.

It is great for running 200 amp. power to your shop.

It is great for the /power utility/ to run a 200A feed to your house
or shop, since they are allowed much larger liberties on derating
ampacity of the wires on their side. Once the power passes the meter
and belongs to you, the derating on the wires is different - depending
on the insulation (60C 75C 90C) it might be only good for 150A or
180A. Even less if you start figuring in voltage drop.

And the code might have big problems with the reduced gauge on he
neutral, but I'm not going looking for the chapter and verse right
now. You can use that reduced gauge wire as the safety ground and
another piece of AL 4/0 for the neutral.

I'm certainly NOT the code expert. I do know its OK for 200 amp service here
in rural Minnesota. Its exactly what I've got.

Bruce,

It is exactly what the power company recommends. In fact, it is the same
brand, type, spec., etc. that they use for 200 amp. service. I already
told them that I was running hundreds of feet and I wanted 200 amp. service.

Right - but that's from the utility transformer to the house main
service. Once you go through the service panel you can't have a
reduced ampacity neutral anymore, and you need a separate safety
ground. You can have a second ground rod out at the shed but the
grounds have to be tied together, no separately derived grounds.

You can use 4/0 Triplex IF you are putting a new service with a new
meter at the shed - then you don't need to separate the ground and
neutral. Normally the power utility supplies the service entrance
wire in California since they are responsible for it. But if you want
to go with larger wire so you don't start off with voltage drop, you
are free to go larger - and should.

Depending on how many hundreds of feet to the transformer, you might
need to go to 500MCM or even 750MCM so you still have 240V at the shed
under full load.

To run a sub-feed out to a shed from the house service you would use
the same stuff but in Quadplex lay-up with three 4/0 and the 2/0
safety ground - the utility would use this for a 3-phase service.

And depending on the distance between house and shed you would need
to derate rather severely - past 200' I wouldn't go over 100A on 4/0.

Bruce,

I have no idea what goes on in California but I would rather not think about
it.

The power company knows exactly what I am doing (boxes and all) and they
suggest what I said before - to the letter.

Now, I hate I2r losses and if I had my druthers, I would run solid silver
buss bar of 500 million circular mills but I don't.

I will go with what the power company suggests and my e.e. education.

I am simply offering some wire for sale.

Thanks

So what? THey have no legal responsibility to provide you with good
advice.

YOu should find out what your local AHJ says. Even though you are
rural no where, you certainly have some one some where who has a legal
authority, and obligation, to inspect it. [And they probably want you
to have pulled a permit and paid a fee.]

Well, I am an e.e. so, I don't really need anyone to hold my hand about
this. I just thought that I would tell Bruce that the power company uses
just what I listed for their installations.

All I wanted to do is to offer others some wire at a very, good price, much
below retail, should they wish to run heavy service to their
shop/shed/building, house, tipi, cave, cavern, tunnel or whatever.

I could also get anal about it and ask the Supreme Court what they thought
about it, too. .

You see, I am not asking for advice although, I appreciate input; I am
merely offering some leftover wire for sale that I almost stole.
