Hi, can you verify the "amp" rating of your bed? 125A would be about the biggest I've ever seen. I'm not saying it's not correct, just an unusually large bed. This is the most important detail in determining the wire size and absolutely must be correct.

it is correct for was a three phase bed which would usually take a 100 amp breaker but since im converting it ,it is 125 amp
Expert:  Mike replied 7 years ago.
Makes sense, just needed to be sure. You'll need either #1 Copper, or 2/0 Aluminum conductors. For the ground you can use a #6 copper or #4 aluminum.

what does the 2/0 mean and is there any difference between using copper or aluminum.

which is used more

Expert:  Mike replied 7 years ago.
2/0 is the wire size, just like #6. Once you get up to 1, the next larger wire is 1/0, then 2/0, etc. Aluminum is cheaper than copper, but aluminum isn't as good as a conductor. That's why if you use aluminum you have to use a larger wire. It's your preference.
