We are a small community heater, three sides, with 9' ceilings, and a well maintained control booth. We currently have an NSI system - 24x2.4kw dimmers hard wired to Edison patch panel which manually plugs to 84 circuits in a legacy 30 year old conduit system (NEMA 5-15R Edisons). All wire is 12 AWG with some shared neutrals - but no signs of stress anywhere. We allow on luminary per circuit, and 4 per channel. Balancing is closely watched (We have active metering of all dimmers to facilitate balancing.) We have a three phase four wire 100 amp service but the packs are derated to 80 amps (6x40 0r 240 amps) (50% face plate) - we can drive 50-60 fixtures (traditional Altman fresnels and leicos) at a time and it is plenty for the space. All our fixtures are 500w - so that is the max precut. We use NSI multiplex controls. We also have a separate NSI dimmer and controller for our track lights (4 three color Altmans in series - chews up an additional 50 amps.
I would like to replace it all with a stack of 72 1.2kw dimmers hardwired to the conduit circuits - about one dimmer per conduit circuit –. Single 500w fixture per dimmer but a twofer here and there is ok. I see no reason to change the mains capacity. We want the flexibility of the many dimmers, DMX soft patching, a modern DMX controller, getting rid of all the extension and patch cord, and be ready for LED lighting.
Assume I have under 20k to spend.
Any recommendation would be appreciated? Brands?
