Building an audio room - 12x22 - electrical plan?

If you think you need 2ea 20 amp circuits - do 4 - MUCH cheaper and easier to do now than later :-)

Place them where you want the equipment to be placed ie if you think you will go for mono blocks down the road, place the outlets where they will be placed. Also remember that you can have more than one outlet on each dedicated circuit. In above example you could place an outlet behind each speaker, both fed from the same breaker.

On wire gauge 12 gauge is required on a 20 amp circuit, but go 10 gauge if you can swing it.


Best of luck on your project and Good listening

I did run 2 ea 220 Volt lines into my room (1 on the amp wall and one on the front end wall) in addition to the 6 ea 120V lines so that I can run 220V equipment when needed. I was however made aware of, here on this forum, that it is not up to code to do so in a residential setting so your electrician may not want to do it for you.

Best of luck

Above link to an earlier discussion about this subject JEA48 gives excellent advise on the code issue of 220V outlets in a residential setting.

As far as running stereo equipment on 220V / 60Hz it is actually easier for a transformer to run on 60 Hz than on 50hz and most of the equipment will happily run on 60Hz. In most equipment the AC signal is rectified as soon as it enters the machine at which point the AC line frequency is irrelevant. If the transformer have multi winding primaries its only a matter of running these in parallel for 117V operation and series for 234V operation.

Some of the larger companies that wish to control where their equipment ends up do build some frequency monitoring devices into their stuff to prevent its use in other markets than originally sold. However without these the equipment would happily work on either 50 or 60 hz.
