Is 15 ampere breaker enough for the home theater equipment in my room?

-Emotiva XPA-5

-Integra DTC-9.8

-Belkin PureAV PF60 power console

-Mirage OMD-28

-Mirage OMD-5

-Energy RC-LCR (Replaced soon with OMD C-2)

-Energy C-2

-JBL E250P which is 250 watt amp soon to be either a JL audio Fathrom 113 or the REL Britannia B1(CANT DECIDE). Primarily music listening but I'm 50/50 for music and movies, but would prefer to lean towards better music.

-Gaming computer, rigged to my system with an 850 psu probably drawing 500 watts.


Since the REL uses 500 watt amp I'm considering using that but I keep hearing rave reviews about the Fathrom 113 but I'm concerned about the 2500 watts rms 'short term' I hear it only uses 800 watts. If that is true Can my breaker support that?


Can someone please help?

I can help you with the answer to your question for about $30. Use the $30 to buy a Kill-a-watt and use it to see what sort of current drain that your system is creating right now. If you can, break it down by individual component. Report your findings back here and we'll go from there.


For nothing, I can tell you that a 15 amp circuit done right won't cause a problem with *any* semi-reasonable home audio system.

I have a 63" Plasma display, a Sherbourn 5 channel amp, NAD preprocessor, Directv HD DVR, Rega tt, phono pre-amp, Nintendo WI, BD player, AV123 MFW-15 sub, lights, and Precor eliptical machine all on a single 15 amp circuit. Never tripped a breaker in 10 years. I had an electrcian come in to give me an estimate for a dedicated 20 amp circuit and they said if I wasn't have any issues with it the way it was, then don't worry. Basically they said if it aint broke no need to fix it.

Single or dedicated? That could make a difference. Also take into consideration that when "sharing" the circuit with dimmers, CFL's or perhaps appliances, you could introduce nasty stuff.


Either way... 15 or 20 amps, whatever it takes.


But, I really am a "pro-dedicated" AC circuit for A/V gear. It can save you a lot of potential headaches down the road.


All one can do is try it (the existing circuit) and see what happens. If you have problems, you now know what to do.

But if I run a new 20A circuit won't it cost >$500 just to have an electrician rewire?


I also have another computer but i dont run it simulatenously with my other comp i use it to study off of, and i also have a printer, 28" lcd monitor, External harddrive, a standup fan, the lights in my room are controlled by a dimmer switch, and theres bathroom lights in the bathroom next to me, also a carbon monoxide detector, and a smoke detector.

Get some quotes and find out!



I would say that you should not have EVERYTHING on ONE 15 amp circuit.

He won't have to "rewire" at all. Run a new circuit. Just gang two duplex outlets, box, wallplate, xx feet of 12/2 romex and a 20 amp breaker. Materials shouldn't be much more than $75. Labor is tough to judge, but >$500 sounds a bit high to me. I could be wrong...

I agree with the dedicated 20A circuit. You really don't know what else is run on the same circuit as your equipment receptacle, so as Ratman stated, just have an electrician run a new wire from the circuit panel. You can then use the existing 15A circuit for the ancillary equipment such as the computer.

Best advice so far, IMO.

yea, way too high, unless the electrician's kid has college tuition due...



assuming that it's not an impossible run, a capable electrician ought to be able to do it in about an hour...

And, I forgot to add, that a load center breaker space is available to add the 20A circuit. Otherwise, the electrician will need to ferret out runs, and junction what is available to free up a space, or add a sub-panel...something you may not want to get into.

That's why we get estimates.


(Or for those that are technically inclined... do it ourselves.)

yes, true... if the breaker box is maxed out, that turns into more work... easy enough to find out by going and looking though...

true dat... and again, an estimate is something that a competent electrician should have no problem providing...


cool... does that mean i can call on you next time i need one?

Nope.


One oops (not being licensed or insured) and my kids lose their inheritance after you try to sue my arse.



EDIT upon a re-read:

Incompetent "electricians" also provide estimates.

Wow awesome, thanks a lot. My friends' friend is an electrician, he said he will come have a look.


So pretty much a 20 amp circuit dedicated for my HT and the existing 15 amp circuit for everything else, right?

It would be a good idea to actually figure out what capacity you might need...


Look at the back of each piece of equipment with a power cord. Add up the watts on the rating plate. Divide by 125. That is the maximum number of amps that your equipment will ever draw (ignoring inrush current). Add to that whatever else is on the circuit and go from there...

Yes!


Your equipment listed above will not trip that 20 amp circuit ever!
