New Electrical Circuit

@hilroy48 The electricians have it scheduled for 15 amp circuit. So a 20 amp is the way to go? What about the size or type of wiring ?

Wow mind blown. Thanks guys. I had to do this out of necessity but excited for the unintended upgrade. 

With regards to the number of plugs , do I just go with the standard 2 and connect power conditioners from there to expand (for all equipment) or would putting a 4 -6 outlet plug be better or even needed? I’m not sure if the high end outlets typically go up to 4 or 6. 

@jea48 My electrical box is outside. Can they encase the (Southwire Armorlite 125-ft 10/2 Solid Aluminum MC (Metal Clad) Cable) inside metal conduit for the outside portion for weather proofing?

@jea48 Regarding the 20 amp circuit, vs a 15 amp circuit, would you not need a 20 amp plug on the amp’s power cord for the unit to utilize the 20 amps? -and what if the amplifier only calls for 15? Would there still be a benefit? My understanding is when connecting the amplifier to a 20-amp circuit that the amplifier will draw only the current it requires.   I guess the question I am getting at is: should I use a 20 amp power cord/ “plug” for the amp to match up with my 20 amp circuit?
