Hello Everyone,
I am building a new home in Illinois and will be running 400 amp service from the street where the main ComEd electrical line is located to my house. Here is the problem, or at least what im worried about, the house is over 600' from the main ComEd line. My question is, what type of cable is going to be required to run that amperage over that distance? i did some quick research and i think the answer is, THE VERY EXPENSIVE KIND, but i read enough that i knew i should come in and ask someone who has experience with this stuff. What i was finding was that i might need a cable called 900 MCM. I am not sure what that is, but i know it is expensive. Is that the type of cable i'll need? are there any other ways to reduce the cost of the run?

Thanks in advance, i appreciate your time and any information you can share.

Mike

Can you just parallel 3/0 copper, in other words that would be four 3/0 for the live phases 2 neutrals. Make sure that you tape the red phases and the other 2 phases leave them black and white tape your neutrals. Do not cross your phases.
