All of the power amps (AR - Paramount Sound) at the Caesars Palace Omnimax stayed on for the entire 20+ years that the place existed. We did power down the dubbers and the non-sync playback each night however.

We used to throw the breakers every night but after 20 years of trying to keep the staff trained on which breakers NOT to throw (such as the one controlling the marquee timer, etc.) I finally had an electrician put in a nice row of wall switches that turns all the essential stuff on. That has eased almost as many headaches as the Film Tech Platter Safety Ring.

I've managed to throw a Zinsco breaker around 50 feet. [Big Grin]

And a Square D about 60 feet.

'sides, aint breakers designed NOT to be used as switches, but more as what they are called..."breakers": to 'break a circuit open' when really needed?

If that's then the case, tonnage of circuits would have relay circuits inbetween the panel and the target devices.

Both.

I have Homelines installed at my apt here, they're not that bad, but def not up to the standards of the QO Series. But still better than the GE crap.

Monte, not sure if that first line was a quote from someone else or your thoughts.

Most breakers can easily handle the on once, off once of a daily shutdown without too much stress.. IIRC the minimum number of manual cycles a breaker must handle to be UL listed is 10,000, which with twice daily operation is 13.7 years.

Also many brands have breakers marked "SWD" (Switch duty) which have heavier contacts to handle switching inductive lighting loads.

I still maintain, based solely on my experiences so far, it is far better to keep the equipment on 24/7.

Where I used to work, by the front door they put in a switch (which was key controlled; the building's master key fit it) would control lights for the whole building minus the booth. Although before safety lights got placed in the stairwell (and someone had prematurely turned everything off), I hated exiting there (esp while carrying cans) cause you couldn't see a damn thing. Got very used to counting the steps.

I can vouch for that. Until we got our wall switches, the same six breakers had been in daily on-off service for at least 25 years or longer, in fact they are still in service...they just have an easier life now!

Turns out the solution to the original problem seems to be to power up the projectors to "powered on" mode ("on" light solid green,) not just stand-by mode, before turning the Dolby servers on.
