That would depend on the voltage. If you are talking about for your house or something, you should have an electrician do it. That long is probably not practical at 240V. For example, if you want voltage drop limited to 10V, at 400A this is 0.025 ohms. You would need wire that is less than 0.011 ohms/1000ft. This would have to be parallel, for example 4 sets of 500kcmil. It is probably more cost effective to travel at a higher voltage, especially if you can get the utility to do it and provide a service at the destination.

If this is for a 120/240-Volt, 3-Wire, Single-Phase Dwelling Service the National Electrical Code 2002 Edition, Table 310.15(B)(6) list the Conductor Types and Sizes. The Conductor (AWG or kcmil) for Copper would be 400 and for Aluminum or Copper-Cad Aluminum would be 600 for 400 Amperes of Service. I would have your Electric Company set a Pole and Transformer closer to your Dwelling. I Hope this Helps.

First thing I would recommend is that you stay away from Aluminum Wire period. Copper is the best conductor for the price and is not as prone to corrosion as aluminum.
You say you are running 1100 feet and need a minimum of 400 amps I would suggest that you would need to get a new service drop to the location. Most residential service is designed to be 200 amps. The resistance in 1100 feet most likely will require a transformer in the line to keep the current constant.
Your proposed run distance is as long as 2 city blocks, therefore I suggest you contact your supplying utility and inquire about service to the location you want to set up.
Good Luck.

You need to consult the National Eactrical Code for the chart because you will have significant voltage drop on such a long run and will have to increase your wire size accordingly. I don't have a code book here or else I'd look it up for you.

Buried or Free Air? Thatt will make a signifigent difference. That said I don't think it would be cost effective or practical to do. The others are right it would be more logical to have your local utility set a new service at the site you need.
