Long distance electric transfer

Assuming this is standard AC power..

You connect your line to 240 power. Two hots and a neutral for your transmission line and then split that into two 120 volt lines at your source. Standard breaker boxes will accomplish this.

However. This will give you more total power...but not if you are just running one device.

For instance, for running two motors this will work much better than splitting a 120 volt line between two motors. But if you are running one motor the advantage is wasted. This is one reason why high amperage devices are usually 240 volts as amps go down and transmission improves as voltage goes up. To run once device you would need a transformer at both ends to up convert and down convert your single line voltage. This is rather expensive for the amps you're talking about.

What are you trying to run?

My current set up is 420 feet of 2-2-4 direct burial cable with 240 volts that I split to 120 at my house....and I also use 240 at 50Amps for my welder, which works fine.

Using this calculator was pretty handy for figuring out my needs.
