I'm starting to do the wiring design for my theater. I've read that you should have the projector on its own circuit (20 amp). I've also read that the lights should have their own circuit (15 or 20 amp) and the rest of the equipment should have a separate circuit as well (20 amp). In addition, I need to power two Paradigm seismic 12 subwoofers.

The plan is to have the projector and equipment circuits in the same phase. What should I do with the subwoofer circuit as far as phase and isolation? Do they need to be in phase with the projector and the rest of the equipment? Do they need a separate circuit as well?

I was considering using a Belkin Pure AV AP51300-10 battery backup and power conditioner to power everything (except the lights). If I use that can I run one 20 amp circuit and plug everything into the Belkin (there are 13 outlets)? What are the pros and cons of doing that?

Thanks for your time.

15A is more than enough for most projectors, you could save $ vs 20A

Yes - same phase, yes - dedicated circuit for subs, perhaps a single 20A or two 15A.

Unless you get a huge industrial UPS, I would use it on the projector only. You want enough juice to shut down the projector and let the fan(s) cool the bulb. Running everything off a small UPS means a single circuit for everything.

YES, COMPLETLY AGREE!!! VERY GOOD ADVICE!!

Dave, great questions and great planning on your part to do it right...

One question though,,, to protect your projector with the UPS unit so it has battery power from it, you will need some method of a power-in using romex to the receptacle in the ceiling at your projector.. right?

Here's a suggestion for the Powerbridge, that is inexpensive inlet/outlet solution I purchased myself for my LCD on the wall to "feed" my surge protector/conditioner to my TV... Check it out, it's one of 2 products I found that will do what you want. www.powerbridgesolution.com
The other is allot more expensive from Panamax http://www.panamax.com/products.cfm?group=22&sec=detail&id=221&ly=h

HDTVlover45,

My projector is going to be ceiling mounted. I was going to install an outlet in the ceiling that had romex running to a normal plug. I would run that to my equipment room where I would plug it into a battery backup/surge protector.

Dave

Okay, here's the plan as of right now:

Projector - one 20 amp circuit

Audio equipment - one 20 amp circuit

Subwoofers - one 20 amp or two 15 amp circuits

Lights - one 20 amp circuit

Room outlets - one 15 amp circuit

I also need to power my Berkline recliners. Should I just plug those into the room outlets or have a circuit for them as well? Did I leave anything out or get something wrong? Please let me know.

Thanks!

Dave

Here is my .02.

I have the Belkin UPS you show and what you need to do is manage what you have on what phase of the shutdown very carefully. I have my receiver plugged in to the phase that shuts down immediately. The projector is on the phase that shuts down last. I have tested it and it lasts about 5min which is plenty of time. If it was an issue, I would have just put a small dedicated UPS in there for the projector.

As for the circuits. I run my sub off the same 15A circuit as my lights without a problem as it uses about 680watts max, but I also knew I could run a dedicated line at any time. I made sure everything was on the same phase for the theater room by moving around lines in the electrical panel.

The berkline chair motors use almost no power, put them on the lighting circuit. The projector doesn't need more than a 15A circuit and you may want to consider pulling 2 20A circuits to teh wiring closet and just feeding it off something in the wiring closet.
