Dedicated circuits
I just completed installing 2 dedicated circuits. After reading several threads here, I went with 30 amp breakers with 10 AWG wire with high end receptacles. One circuit for the amp and the other for everything else. I’m blown away by the difference. Tighter bass, not as bright, better imaging and soundstage. Should have done this long ago.

If you have an electrical fire as a result of your non-NEC code compliant installation, your insurance can deny your claim. In order to make this code compliant, you need to put a 20-amp breaker before a 20-amp receptacle. I think folks should be careful of offering their non-code-based suggestions regarding how to install electrical circuits in a residential environment. See discussion on this point at the below electrical forum of Mike Holt's electrician code training forum. Can I put a 20 amp receptacle on a 30 amp circuit? | Mike Holt's Forum

@dpop Wow!! That's a 30 amp plug alright. I'm confused by your comment. The specs on the crown amp show it's draws 0.75 amps at idle. My Hegel H30s put out the same power as the Crown. As I stated above, the entire system in operation draws about 3 amps. Here's an interesting video from PS Audio on Damping factors. |
@nmolnar , if a 15A breaker was in front of a circuit that was made of 12-2 Romex and 20A outlets, wouldn’t that be safer? I mean, the 15A breaker would trip way before the 12-2 or the 20A outlet got hot enough to catch fire, right? I ask this with no intent of sarcasm whatsoever--I would really like to know. |
Yes, in theory your thinking is correct and as long as the installation is up to code (which it may be) in your area, you should be fine. Remember that local electrical code inspectors can vary in their understanding and interpretation of electrical codes, which can vary a bit by location. The one issue for the discussion is that a 20-amp receptacle has a physically slightly different plug configuration which implies it is connected to a 20-amp circuit. Someone may be misled when they see a 20-amp receptacle thinking they can use a 20-amp rated device. Of course, the 15-amp breaker would trip if the 20-amp device were to overload it so there should be little to no risk of an overload causing a fire. **Disclaimer-I am not a licensed electrician** |
