Thanks
Rick, my furnaces are three phase, 208 volt and each has it’s own 125 amp breaker. We ran 2/0 copper wire. It’s been awhile since we set this up. I think originally they were pulling something in the 90 to 100 amps range. I think I dialed it back with the current limiter just because all those amps made me a little nervous. We eventually got them running smooth and I went on to other things, so I never went back and rethought the amp settings.

I find myself a little reluctant to post this info. I went to the handbook to size the wire and then had my Electricians figure it too just to be sure. If you’re thinking of wiring a furnace you should also rely on the handbook and not what I’ve done.
