What kind of regulations are there on dimmer
patching? Where would I find what those are?
Where are you ?.
I'm suspecting the UK and would recommend moving the questions to the Blue Room www.blue-room.org/uk
, a pretty much UK oriented forum, as they are more knowledgeable about UK and Euro issues.
It sounds like you need totally new dimmer system
and your going to get a dimmer-per-circuit system
, for however many dimmers you can afford. You *might* be able to hookup
the new dimmers to the existing 36 circuits, if the powers-that-be are of the opinion that the existing wiring is in good enough condition to keep in use. That saves money. Having an Existing Express
is a good thing as it's a good, serviceable console
. If budget allows, maybe upgrade to Emphasis for the additional channel
capacity as well as many additional features.
Not sure of the UK, but here in the states, the National Electrical Code (which is not mandated for local jurisdictions to follow !, though most do) allows you to install a ETC
Sensor 96x2400kw dimmer rack
on 10 amps ! - I.E., the way the code is written is you do not have a "Connected Load" power
requirement, but instead can use a "Demand Load" to factor in power
The reason for this is that having a theater with 600 x 2.4kw dimmers @ 120v - 3 phase
would need a feed of 4,000 amps per phase
, if Connected Load were used (600 dimmers @20 amps ea. across a 3 phase
). The Theater/Entertainment folks on the US Nat'l Code Committee realized this was generally impractical, as very few facilities loaded every dimmer
to near max. Usually it was many fewer circuits actually in use with single unit
loads @ 575 watts or so. Thus the code became more practical
and essentially tells you to plan for demand load.
So you need to check on what your local codes require, as well as is there supplemental power
available, of sufficient quantities to feed the dimmers planned.
