LOL, I never burn them all at once, but it's there if needed.
When built it, I wired it off the house drop for 200 amps....I installed 22 duplex outlets in the ceiling, and one on every other wall stud all the way around..Then added 6 220 outlets- two on each of the side and rear walls....I recently added a 6-50 NEMA welder outlet.
I got all 15 4' fixtures free from hospital being torn down.....actually I got about 30 of them and scrapped the ones that didn't work...over the years the ballasts started failing so I replaced all ballast with Workhorse 3 T8's and GE4100 tubes.....down the center I already had six 4' junction boxes, so I removed the covers and installed screw bases for the 200 watt CFL's. The lighting is on 3 circuits-back, front and center where the center runs perpendicular to front and rear.
So for about 250 bucks, I turned night into day and reduced my electric bill.
I built the shop 20 years ago when copper wire was cheap, so the whole thing is 12AWG, with 8 on the 220, and 6 for the welder......when I salvaged the lights from the old hospital, I also picked up almost a hundred 20 amp hospital grade outlets, so all 120VAC is 20 amp rated.
