iwire, thanks for catching the math error. I was only thinking single pole breaker. But with the 20 amp double pole breaker you can run up to 3840 watts. So all of these replies have helped me determine that using the higher voltage will decrease line losses, increase efficiency, keep voltage drop to a minimun and allow more of the light fixtures on one circuit. Can I run #10 copper and install a 30 amp double pole breaker and put them all one one circuit? Thanks for all the replies!
