If I can sum up, you want:
1) To eliminate the many runs of
Soca from
deck to assorted locations on the
grid
2) Be able to use that
Soca/
breaker panel
system to
A) Connect 208v
power systems, ML's
etc... at
grid level from
deck level power distro.
B) Provide for dimmed 120v circuits from
deck mounted
dimmer packs
C) Provide both of the above to touring events when they come to the theater so as to speed up the process of getting the multi's run from
deck, to
grid and down to overhead electrics.
D) Running the circuits into
conduit as
THHN eliminates "some" of the de-rating issues that apply to multicable, especially those
bundled together to look neat and clean.
I think it's going to prove to be an expensive install. You need a
Soca male panel on
deck, a custom
circuit breaker panel - either 2 pole (likely) for the circuits,
conduit and wiring
deck to
grid, a
Soca female panel at
grid level.
A big question. When a
deck level feed is 208v how do you indicate that at the corresponding
grid level Soca receptacle, as opposed to the times it's a 120v ?. Concerns with that.
I understand the desire for maximum flexibility but I think it's an expensive
system. Maybe prioritize the need. 208V needed the most ?, dimmed circuits to
grid ?, traveling show circuits to
grid ?.
I'd be thinking about
grid level 208v
power distro from a CB panel, having 120v in that as well for
LED. I think your going to see fewer and fewer dimmed circuits in the future, including off
road shows, where it makes sense for them to do
LED and movers.
Not sure what the in-house
system is like or the plans for the future in terms of replacing
incandescent with
LED.
