building a new house, currently have XPA-5 gen 1, likely will add a 7 channels amp to do atmos setup 7.1.4, also likely to buy a new subwoofer like HSU VTF-15H MK2.
How much electricity power do I need?
Normally each wall outlet has 15 amp?
it is $325 adding a dedicated wall outlet for 20 amp...wonder if I need it?

Since you are building a new house I would go ahead and add some 20 amp lines in there for the future. Future proof it. I sure wish I had the choice to do so when I bought my house.

If your building a house or adding on, $325.00 per circuit is cheap compared to doing it later! Do it! |

I'd go for it. I doubt you'd ever be short on power without it, but it's nice to have a clean circuit that doesn't have noise from other junk like dimmers and computers.

DEFINITELY, not even maybe.
Separate- isolated hot, neutral & ground to its own breaker
I believe $325 is too high, but... Using an additional breaker, 12 ga, not 14 ga

That seems high but it could be a long run.

$325 isn't high at all, material and labor plus license and insurance for a qualified electrician. Don't cheap out unless you are doing it yourself as a qualified electrician.
You can pay $325 just to have a ceiling fan box and switch installed.

I have three 20-A circuits in the front of my media room, plus a 15-A run around the sides and back, plus the light circuit. I really wish I had added another 20-A drop in the back now that I have added rear subs but it would be prohibitively expensive (dedicated room, finished basement now, floating walls/ceiling, not a simple pull). At build time the cost is for 12 AWG instead of 14 AWG wire and higher-capacity breakers so the additional cost is usually minimal. The extra drops cost more and is probably where the $325 is from. For a new build I would put a couple of outlets on one 20-A run on the front wall, one feeding a couple of 20-A outlets on the back wall, and a third 20-A circuit feeding the outlets on the side walls. That should make all the outlets in the room to 20 A breakers and provide the capacity to handle where ever you decide to place the equipment after the build. You always need one more outlet...

For a 15amp circuit with 14 AWG wire the voltage drop due to 40 ft of wire is 1.5V at rated current. For a 20A circuit at 40ft, it is 0.95V. I have not heard of one person on this board having issues with breakers tripping from overloads due to AV equipment and I doubt a 1 volt drop is detectable in audio output. Your best bet is to use a good line filter with surge suppression to protect your equipment. If you want to gauge the noise on your home power system, crank up the volume with no input and see how much "noise" is passed through. The noise is either your equipment or your source.

Hmm that's odd ,I've popped many a 15 amp breaker running my Emotiva XPR-1 monoblocks ,XPR-2 amp and MC-2102 on a triamped line array ,I have 3 pairs of amps that will crush a 15 amp breaker ,or limit the wattage the amp can put out by not having enough juice available at the wall ,when you buy Emotivas biggest monoblocks they come with a 20 amp power cord so you can't even run them off a @5 amp line . |

TOTALLY disagree It's a new house being wired, the guy is there wiring the whole darn house $325 to run 12ga instead of 14ga, 20 amp receptacle and add one more breaker? give a break. |

You could always do it then? Edit.. That sounded personal; however, it wasn't meant to. |

I just purchased six pieces of Emotiva equipment, RMC-1, two XPA-DR1, one XPA-13.1 and two S10 subs. I ran six new branch circuits using 10/3 with a ground and added six Leviton 5842 125V/250V 20A dual voltage receptacles. If you are going to add or upgrade the electric, might as well make it 125V/250V. Also, the voltage drop is less with 240 volt service. My branch circuit runs are 85 feet and the 125 volt voltage drop was too much with 12 gauge, but 12 gauge was fine for 240 volts. I opted for the dual voltage 125/250 using 10 gauge. The Emotiva manuals say best performance is achieved with 240 volt service, that convinced me. Labor is the same whether it is 12 gauge or 10 gauge. Now I have six 125 volt outlets and six 240 volt outlets. With dedicated audio branch circuits, my family room lights and bathroom lights don't blink with the bass anymore!
