What I am trying to do is use a transfer panel to power some 15-amp sockets with ether a dimmer pack, or from the main. (trying to set up a theater space so when there's not a show going on you can plug sensitive things into the walls) Can you do this with a transfer panel?
More info: There are 4 sets of 3 outlets (set A, set B, set C). Each set has 2 circuits, and each circuit is rated for 20 amps. (some of the outlets are tied together, it's a bit confusing due to the fact that the space was built in the 40's, how long does it take for the plastic/rubber shell on wires to get go bad?) I want each circuit to be switchable, able to run off the main panel, or run off dimmers that run off the main panel (theses are the big dmx controlled dimmers you would use for theater or djing, they give out 4800 watts @120V spred across 6 channels). Everything would run a at 120V although I can get 240V. Even though its inside a building we get main lines (L1, L2, and a neutral, just like you would get from the street pole), this comes from a sub breaker room, that comes from a transformer, that then finally comes from the street. I'm pretty flexible as in to what the plan is in the end. Sorry if Im just repeating myself, felt that the first Q. was not adequately expanded upon, so I just restated it.
Edit2: Well at least I think its from the 40's but it probably din't go in at that time, there was also some retrofitting in the 80's so any sockets and switches were replaced, the sockets I want to power are ground level, there are no sockets on the ceiling, power goes straight from the light board, through the walls (brick and morder), to "junction boxes" on a grid on the ceiling of the stage. If you can identify the model of the light board I'm planning to take out, that would help me a lot. All I know is that its a Zinsco. And yes, it is used without problems, although it does give out dirty power (have not checked with an oscilloscope, only know by experience). I most likely am going to have to hire an electrician, but I would still like to have a solid plan. Also, as far as I know, and I have searched high and low, any electrical floor plans for the stage do not exist.
This thing also acts as the main panel for half of the building.
