20 amp H2O heater line
I had a disconnected 220 water heater line that was already run off the main. I studied others who had 'mistakenly' connected a 220 line to the A/S and blew everything.
So I ran the line out to my work shed (using an 8 gauge) and installed a second box where I split the 220 to 2 - 110s. I ran a 20 amp breaker to my waterproof box for the 30 amp plug outside the shed for my A/S plug. I am using the rest of the 110 for the shop tools.
I know that the water heater line won't run the A/C AND the radial arm saw (on startup), but the volt meter doesn't show much drop with the A/C on.
I also fixed up a pad for the A/S with concrete for the wheels and mulch for underneath - (no grass would grow there for sure!).
Sure is nice to have things ready for use!!
