View Full Version : Power requirements and whats available

Hey all,
I've moved recently and in my new place built in the early 50's I have very limited outlets, and a very slim chance of modifying or adding anything electrically....

My questions are:

1. Plugging an AMP (B&K REF 200.2) and Reciever (Denon 3803) , and an 8" Sub into the same outlet. How bad is that? There is a chance to run an extension cord about 10 feet and connecting one seperately say maybe the amp. But then all my input devices would be running on the same outlet as one of the others. But then I do have some quite nice power conditioners that may make that a non issue.

2. OK I hear about alot of people putting in dedicated 20Amp lines for their gear.

Is it enough if a couple of the outlets are on the same breaker and upgrading the breaker from a 15 Amp to a 20 Amp. Of course the wiring would have to be up to speed at least 12 Guage I would think, maybe 10. Would this give me the same 20 amp availability? Of course without the dedicated line to prossibly reduce any noise (which is what the power/line conditioners are for). Should I think of this as an option? easy cheap, more available current and amps???

If you all can provide any support it would be very much appreciated.
I'm Really curious about the questions above,

I'd recommend adding a Richard Gray unit if you're concerned about power. 2x400S or 1x1200S should do the trick nicely. You can read about them here:

Here's a thread from where I asked a similar question when looking at a house built in the early 60's.


I discovered that I would have had to upgrade from a 2-wire electrical system to a 3-wire system (hot, neutral and ground) to be able to use surge protection. The old 2-wire system only had hot and neutral. We were going to renovate the home so the electrician and contractor were going to be able to work together to get at least one grounded 3-prong outlet in each room. Our deal fell through and we found something built within the last 3 years.
