High Current Outlet for Amps?

 Your homes physical location on the utilities grid can result unique noise issues that may require specific filtering or regeneration. The same goes for RF issues.

I found in my remodel that increasing the service amperage from 200 amp to 400 amp came with a new run of cable off the utilities grid. 

I used 20 amp breaker's in the new service panel but I loaded 10 gauge wire within metal BX conduit uninterrupted to metal  receptacle boxes (which may not be code in your area) to deal with RF issues in my area.

I doubled up the solid core ground wire from the new panel to a new larger and much longer ground spike. Not only were my RF issues gone but I noticed improvements in most all of our electrical devises. 

I had dedicated circuits put in (2 x 20A for my amps, and another 15A for my source components) and would recommend it.  My amps draw a lot of amperage but more importantly is that the circuits are isolated from other sources of noise that share the same circuit.

It's a no brainer if you are already in a remodel IMO.

The 20 amp receptacle is the same as the 30 amp one!  No difference at all.  You are just running 10 gauge wire connected to a 30 amp breaker in the service versus a 12 gauge wire connected to a 20 amp breaker.

A 20A device on a 30A breaker doesn't meet my local codes and probably isn't consistent with NEC, either. 

I respect the comments/consideration on high current draw;however,I had a local licensed electrician come to my home and measure current draw to my amp & preamp with my system powered up while i listened to rock and classical orchestral, with my approx 88 db efficiency speakers and 200 watt amp, at levels higher than I care to listen. His measuring device didn't exceed approx 3 amp draw. I used 10 gauge wire and a 20 amp fuse. I did not sense any problem. Is this unusual?

My power amp is plugged into high current outputs of Furman Elite 20PFi conditioner that is able to deliver 55 amperes peak current.  They call it Power Factor Correction.  It is achieved by huge inductor followed by big capacitor that stores energy.  From the mains it appears as resistive load (current spikes are filtered out - averaged).  I don't detect any loss of dynamics.
