My wiring is going to be off of a 200 amp main panel located by my wells. I'm going to be making 4 runs off of it, 2 will be going to my 2 wells and the other 2 will be going to my shop and trailer. They will be 4 wire runs(2 hots, neutral and bare copper ground) inside of SCH40 conduit buried(local building department said I have to use conduit for a sub-panel), nothing really complicated. The actual feeder to my 200 amp panel will be 2 4/0 pieces of aluminum and a piece of 3/0 for the neutral since the local power company uses aluminum wire in there overhead runs. I've just heard to many people talking about ALUMINUM breaking inside of the conduit because of heating and cooling expansion. Just looking for advice on it. I personally want to run copper, but $1K a roll is a steep price tag.
