[QUOTE="Tim McCulloch, post: 115593, member: 67"] Re: X32 v2 RTA Well, it's not necessary or even common to have sound and lights on separate "hot legs." Nor is it necessary to have these services on separate transformers.... as an Arena Electrician I find several different setups: in our old county arena each company switch has its own transformer; in our new country arena, 1 big transformer for each corner of the arena supplies multiple company switches/disconnects - 2ea 400A 120/208 6 wire services (double neutral) and 4 ea. 200A 120/208v 6 wire services. In 4+ years we've connected video, audio, lighting and carpentry automation to these services without interference or incident. The 120/240v "single phase" is more correctly "split phase" because it's a center tapped secondary, with the center tap (neutral) bonded to grounding electrode system. Mac's definition of the term "single phase" meaning how the step down transformer is powered is the correct usage. I suggest Richard Cadena's book "Electricity for the Entertainment Electrician and Technician" be added to your library. [/QUOTE]
