20A vs 15A Power Conditioners and can I even use a 20A one?


Hello all,

I am interested in adding a dedicated power conditioner for my power amplifier + subwoofer alone and have setled on either the Furman IT Reference 15i (15a) or the 20i (20a)

First of all, I know the outlet I use is a 15a outlet, but it does run back to a 20a breaker. I could swap this out to a proper 20a outlet, but I have heard if you are installing a 20a outlet, there should be no other devices running on this circuit and it should be dedicated. (This won't be the case) Also that there is a chance the wiring which runs to the 15a outlets (even though they go back to a 20a breaker) could be not equipped to handle 20a and could be a safety issue. Can anyone elaborate on this?

Will there be any sound quality difference, especially in regards to dynamics with the 20a vs the 15i version? I have seen many power conditioners with poor handling of dynamics. I will be running a 200WPC amplifer and a 370W powered subwoofer on the conditioner.

"but I have heard if you are installing a 20a outlet, there should be no other devices running on this circuit and it should be dedicated."

It is best that any AC line feeding your audio equipment be dedicated (at least not shared with noise-generating appliances), but this is no more true of a 20 amp than a 15 amp line.

If you are in any doubt regarding the proper wiring requirements for your AC lines, consult a licensed electrician.

You didn’t ask, but I owned the Furman IT-Reference 20i and there are several other conditioners that offer much more sonic improvement FWIW.

First the in wall branch circuit wiring should be at least #12 gauge for the circuit to be 20 amp. And it may very well be #12. Two or more 15 amp receptacles can be installed on a 20 amp branch.

20 amp receptacles can only be installed on a 20 amp branch circuit. You can mix 15 amp and 20 amp receptacles on a 20 amp circuit.

Not true. In a commercial building or industrial facility you can install up to 13 (20 amp duplex receptacles on a 20 amp branch circuit. In a residential dwelling unit there is no limit on how many 20 amp duplex receptacles you can install on a 20 amp branch circuit.

dlcockrum,

What other power conditioners would you reccomend I take a look at again? Again, I need something just for the amp/sub. The other gear is running off of a PS Audio Power Plant Premier, which while good, I find significantly reduces the dynamics of the power amplifier.

Thanks.
