I'm about to start a project that has an area with 45 hi-bays. Each hi-bay has six 57W CFLs, with 2 lamps per switch leg to give a dimming effect.
I just want to make sure I cover all my bases for a proper install.
Without taking into consideration the ballasts' effect on the amps/fixture, is it safe to just go by:
57W x 2(per switchleg) x 45 (fixtures) / 277V = 18.52 Amps on each phase
Would it be acceptable to use three 30A OCPD circuits extended to a bank of three 30A rated switches which then extends to each of the fixtures. Each fixture will have a 30A rated 4W+G cord and plug for disconnecting means.
Thanks for the help like always!
