It's a bit more than I wanted to spend to be totally honest but felt like I had to go for it to have the piece of mind like you say, not to mention additional safety. It looks like w 4-1,000watt ballasts on 240v will pull just under 20amps in total, which will be all good on a 10g 30amp circuit.
Thanks again to everyone who helped out with this!
And Ill bet your power company sends you a Christmas card!!
