Outlets and Wire Gauge? - Please help!


I finally contracted an electrician to run two dedicated lines - a week from today! I have been reading thread after thread and the consensus appears to be going with 10awg wire for the 20amp run. My problem is two-fold:

  1. I'm stuck selecting an outlet because the electrician says that no 20amp outlet can take 10awg, that "10awg is for 30amp outlets".
  2. I'm stuck selecting an outlet because of what it might do to my sound. 

I simply want to install something good that's going to feed a Puritan Audio PSM156. I am now running ADG Gran Vivace monos. I prefer a rich midrange.

Additionally, I asked for both a 15 and 20 amp run. People suggested I do this so my sources can be run off the 15A with amps / subs off of the 20A, but someone here mentioned ground loops? I am not well-versed in things electrical. Ideally I would like to know if I should stick with the two runs, and what would be a few good choices for each outlet if I do. @jea48 @erik_squires ... I have seen solid advice from you on the topic of outlets, but they lack things specific to awg and outlet type.

Thank you in advance!

PS I estimate the length of the run to be approximately 50', max.

is 10awg existent inside your amp or inside your speakers, once you're past the binding posts?  

 

@curtdr yes to both questions, my apogee duetta 2 speakers have 10awg and my amp has very little 10awg wire, most of the connections for the output stage uses copper buss bars.

10AWG is a good choice for high end audio equipment. It also provides the additional benefit of allowing you to plug in an extension cord and charge your Tesla when your system is idling in the "standby" mode.

@erik_squires what do you do for a living? You are the man with this electrical code knowledge. Excellent thanks for taking the time to explain the complications of electricity. I wish I had your knowledge. I think it would take a lifetime to completely understand the electrical book
