No matter how well you glue it, moisture and water will always get into underground conduits. That's why the NEC® requires the wires installed in conduits underground to be rated direct burial.

Man, I sure wouldn't announce that in public, you'll have those unruly copper theives digging up your yard. You sure thats not AL wire?
Amen to that. I could build a shop for what that probably cost

Cliff wire sizes double in diameter as you change size. the sizes go from ( just to pick a random starting point) 10, 8, 6, 4, 2, 0. with each smaller number being twice as big in diamater, then it starts back up again with 00 (2/0) 0000 (4/0) etc with each increase in the number of zeroes being a doubleing of the diameter when he says 4/0 that is just a shorthand for 0000 eventually it gets to where you just give the dimensions of the wire itself.Cliff_Johns said:

I saw the website thank you for the information. I am curious in the website it says you used #2 aluminum with a 100 amp breaker. I did not think that #2 aluminum was rated for 100 amps I figured you needed at least 1/0 or 2/0
or did you mean you used 2/0 wire ?

It was - AL-URD Cable 3 Wire 2-2-4 100AMP... that's right from the Crown Electric receipt... which was right from what the electrical inspector told me to buy...

buying what the electrical inspector tells you to is always one of the best ways to go. I am not an electrician so I would not try to tell someone they were wrong. Everything I read says that you have to go two wire sizes larger for aluminum than copper and if you are running 100 amp in copper it takes a size #2 gauge. Maybe one of the guys on here that have years of electrician experience can enlighten me.

I put in ~60' of triplex 4/0 AL 200A underground and 150' of #2? triplex AL 100A underground this spring for my barn and trailer power....
You can balpark the 4/0 at ~4$ per foot and half that for the #2.... Copper is about 75% more.
To reloacate my meter base off the old house the is comming down i had to
set a new pole
move the meter base
buy a 200A disconnect for at the pole
buy wire
buy conduit/fittings for sections that stick out of the ground at the ends
rent trencher
pay fee to have utilty hook me up.
grand total on my project by my estimate is nearly $1000

Maybe it would but since I really dont need it I probably will not buy one. However from what I have been told and what I have read aluminum wire will not carry as much current as copper wire. That is why you need two wire sizes bigger when you are running aluminum. If that is not the case I would welcome someone that knows explaining it. That would probably be more helpful than the comment that I should get a code book.mudcat said:
