Howdy, We're adding a multi-use Dance Studio / Black Box Theater to our Dance Studio facility. The building owner is putting 200A 3-phase power dedicated for this room, 60A of which will be spoken for by the new HVAC system. By my reckkoning, that leaves 140A remaining for potential Lighting system use. All other service in the building is done through a seperate single phase panel so there's no potential other use for the 3-phase. The performing / studio space is pretty small, about 1500 sq. ft. and when doing performances in there, we'd expect the area needing lighting to be no bigger than 20' X 30'. Preface - We will be talking to a lighting supply house / electricians about this but I'd like to have some idea what I'm talking about. First question - Is 140 A 3-Phase service going to be enough? Second question - Any recommendations for best practice on interfacing the panel to dimmers? Cam Lok? Direct? Third question - What 's the most cost effective approach for dimmers? Wall mount, rack mount, portable? Last Question - Any specific recommendations for dimmer brands for something like this? Thanks in advance!
