Some of the pieces, especially factory plug and cord are sposed to be on the circuit they came plugged with. Not all 240 equipment is allowed on 50A breakers. The internals of many machines rely on the short circuit protection of the proper breaker. Ideally is to make for a method of addition when you get something new and add the right circuit or plug it in to the proper one. We could use 10 wire and 30A breaker for 120V,,, yes it protects the building wire but all the **** ul listed is designed to be current limited for 20A.
Small welders, will run on 30A service but come 50 end,,, have features to allow it to be plugged in to common 50A welder outlets.
Welder, plasma, band saw for starters and I'm sure more to follow as things find there way home.
I got a lot of stuff. I live rural single phase and have been limited this way but I am kind of past it at this point and I do have some 240 equipment on dedicated circuits but a lot of the general use **** have 120 if it will go that way. I don't really use anything that would overheat a number 10 wire.
Even a lot of the remote or field welding is done 120 anymore.
