I’d like to install a 240v/50amp branch circuit in my garage. Is this ok? As per NEC Article 210.23(c)- 40 50 amp circuits are permitted in other than dwelling units. Is my garage considered a dwelling unit? Looking at the definition in Article 100, my residential garage is not a dwelling unit. What do you think? (I just want to make sure).
Also, I’ll be using this 50amp branch circuit to power a 15hp rotary phase converter rated at 230v/38amps, 60hz 3phase. It will output 10hp at 3phase from the 240v/50amp single phase input. It will power my pressure washer rated 206-260v/25amps, 60 hz 3phase. Can I do this in my residential garage?

I Can’t see why not, however if your going to plug in the rotary phase converter whats going to allow it to start? doesn’t have a start up load much larger than 38amps?
Also what kind of protection are you going to provide to protect the power washer.
There is no doubt in my mind that the NEC will allow a 50amp 240v recp installed in the garage. I have installed hundreds of them. Mostly for a summer kitchen (range) or a welder hook-up
sounds good as long as you don,t try to run every thing at once,
Yes this can be installed in your garage. I would look at getting a varriable frequency drive for your equipment. You can conver single phase to three phase but will be using less watts to run your equipment.
