I am in the process of designing a small portable rack. It will consist of 2 12x1.2k dimmers, and 6 or 12 edison circuits. I am debating on wiring it for single or 3 phase and need some help. What happens if I wire it 3 phase, and I go to a venue that has only single phase? Should I do one dimmer 3 phase and one single, and have 2 separate inputs? How is this normally done?
