Heya guys, I've got a bit of question dealing with the NEC. I am in working with an architect for this community theatre, and we have been trading e-mails with management level personnel, and he as brought up the NEC in regards to our lighting.
Anyone heard of this in the NEC? Do we, in theatre, using dimmers fall under different applicability? Bonus points if you can write a detailed explanation, siting codes. If the professional architect stresses his point, we will not be able to use two 500W Fresnels on one circuit/dimmer, let alone 575W Shakespeares, or an assorted wattage of track-lights.
I'd really appreciate the help guys.
Thanks.
I have a little problem with the math.* I think the calculation should be like this:
Natl Elec Code limits us to 80% of the capacity of the circuit.
80% of 1200 W is 960 W
960W / 75W per lamp is 12 instruments (OK)
960W / 150W per lamp is 6 instruments (oops)
