    What wire size do I need to run for a spa?
    I have a 230 volt spa that runs off a 50 amp single phase breaker. The length of wire I need to run is about 135 feet. What wire should I use?

    What do the instructions say? Probably #6cu.

    Can you elaborate a bit on this installation?
    Inside?
    Outside?

    Do you know ALL the important codes related to wiring a spa??

    The instructions say "at least #10 AWG" and the wire should be "four-wire electrical service (two line voltages, one neutral, one ground).

    The spa is outside, but on the other side of the house from the panel. I was going to go up through the atic and back down.

    The codes for spa are VERY specific and VERY important.
    I suggest getting hold of a few good books to help you.

    Sorry, but IMO this is really NOT a DIY project.
