Hello Collective, I am speccing some dimmers for a small performance space currently being built. I'm looking at getting a used Sensor+ touring rack with 24 D20 modules. Where I am getting tripped up is that I am being asked to give a general idea of how much power will be needed for the rack. 48 x 20A = 960A, right? The dimmer rack has a 400A service mains switch. I feel like I'm missing something very simple here.
