What kind of romex to use

76.100.115.223

I am going to run a dedicated line to 2 mono block amplifiers from the service panel. What gauge romex should I use? It's an unfinished basement so, there's nothing, other than stuff, read junk, in the way. 10/2, 10/3, 12/2, 12/3. It will be running along the ceiling framing of the basement and will pass under the refrigerator (bad idea?). It will also go past the HVAC system and water heater. Any suggestions on how to route or something to sheath it in to keep the rfi/emi from creeping in?
Thanks, I do appreciate any assistance you all are willing to provide.

Some observations from a non-electrician.

-Check code requirements concerning amp(eres) per foot of run to help determine gauge-the fact that you'll be running one amp(lifier) per home run in a residential setting almost assures that 12 ga will be fine, but you can always go larger if you desire.

-Assuming you have a modern wiring system (including panel) with a separate earth ground, you'll be running XX2 w/ ground (hot, neutral, bare wire ground). Even if you have an older home without a modern panel, I'd run XX2 w/ground and think seriously about updating your home wiring.

-Unprotected Romex in a living space is a code violation.

-If by 'running underneath a refrigerator' you mean running the wire on the bottom of a floor joist with a refrigerator on the floor above, I doubt that would be a consideration (especially compared to having the fridge plugged into the same line!), but others may differ (vibration, etc).

If you're having a licensed electrician do the work, he'll explain all of this in full. If you're doing the work, I'm just tossin' out some thoughts. Should be a big sonic improvement when you've finished.

How long is the run?

Would it be possible to run the Romex on the bottom edge of the ceiling joists?

Do you have a ground rod near the panel?

What I did was to run the Romex inside a steel conduit that was grounded at the panel end to help soak up EMF and RFI from hitting the Romex

I used 12/2 with a bare ground. No need for four wires

  When I ran separate AC leads for my system...I used the largest gauge ...10, I think, that I could find. I made sure that the electrian didn't tie grounds together like they are prone to and got the best AC outlets I could fine...in my case Furatech I think...then use version of Cardas wire with Furatech plugs....seems to work nicely for me.
