I sent an email to a local ME but I thought I'd get good responses here too. For an upcoming show the renters want to put 2 of our follow spots in two of our box booms. There is not a 20a circuit anywhere close to the position. We have plenty of open dimmer circuits in the box. We have two Constant Current Units that we can use. So the spotlight would not be running through a dimmer. They are Lycian follow spots, on the ballast it says its rated for 20a. The Sensor + constant current units are rated at 20a. I would have to put a 20a plug on the 3pin to Edison converter. The thing I am worried about is pulling too much from one leg. The circuits would not be next to each other, so in theory I can put them on different legs. Is it alright to run the spotlights through the dimmers? Or should we run dedicated circuits to the boxes?
