[SML] Relays vs. Traditional Circuit Breakers for LED Power.

[Kristi R-C]

I suspect your suppliers are suggesting "breaker" as opposed to "dimmers" for the LED fixtures and the confusion is in the terminology being used not the location or type of the breakers themselves.

It sounds to me like someone is trying to sell you a very exotic bill of goods that you really don't need and could do much cheaper and probably have better reliability a more conventional way. (Standard regular circuit breakers and a relay pack (though I really see no need for the extra step of a relay pack.) I assume all the fixtures are standard theatrical brands and DMX controlled. A nice large 'company switch' (AKA Bulldog) preceding the permanent breaker panel Is all the good night switching I would want for the breakers.
An inspector would really raise an eyebrow if you were regularly switching on and off the breaker for non-fault reasons.
