I mean, in demo, I've heard of filling the conduit up with red dyle
and water, and blowing it out of what panel it leads to, but yeah. If
the compressor is yours for a day, anyway. But #2 wire probably won't
pay for the operation, like that 500 would.
(gimping 500 wire is where you really start to put your money on)
