Elliot...
While I'm no *licensed* electrician and *did NOT* stay at a Holiday Inn last night...
In a previous life I've done a bunch of wiring (professionally) and added a 50A breaker and 50A "welder" recpt. to box at home. Since the total load on the panel was WELL under the 200A rating (keeping in mind 80-85% of rated is "full"), I had to throw a couple piggyback breakers to handle a couple of lighting circuits to make room for the 50A breaker. Let me know if you can use a hand... I'm not far away K'Vegas
And to fuel the flames... I've been bit by all the major AC voltages (480, 220, 110). While felt that great, a little zap from a 100VDC speed controller has my vote for the biggest "weiny wilt"! Knocked me several feet away after making my body convulse for a second or 2...
