15 amp circuit VS. 20 amp Circuit

Hello,

I’m in a situation where my audio room has one ( three outlets ) 15 amp circuit. It appears to me that the 3 outlets in this room are connected in series , meaning drawing current from one outlet will drain the other two .

For 2 channel audio , I have connected my C12000 pre amp, McD12000 and through MPC1500 conditioner and to one of the 15 amp outlets . This should be okay? However, problem could arise once I connect the McIntosh 1.2k power AMPs to the other 2 outlets.

I would like to know if I need any dedicated circuit for my equipment . It appears I need more power than 1400 watts ( 15 amp circuit can provide ) when I use my home theater Where I will have Four 1000 watt woofers and 3 additional AHB2 amps.

 

 

Question :

howmany dedicated 15 amp or 20 amp circuits do I need to ensure smooth power without dimming the lights around the house / prevent possible fire ?

Please provide your suggestion based on the below equipment .

 

DAC: McIntosh MCD12000

Power Conditioner: MPC15000

preamp : McIntosh C12000

AV Processor : Marantz 7015

power AMP: Two McIntosh 1.2k

power AMP: Three AHB2 , one used in MonoBlock

Streamer : One Streamer

Spoke with a friend who is an MIT graduate. And we agreed , based on the power and the amps of 1.2k amps, we need to have each amp its own dedicated 20 amp circuit .( the benchmark amps can be connected to the same circuit )

 

subwoofers will share , two 20 amp circuits or one 20 amp circuit.

rest can be connected to a regular 15 amp circuit.

 

for those who suggested , minimum three 20 amp circuit for this equipment .. congratulations, you nailed it .

I just had a Electricion intall a 20 amp breaker for a dedicated line with a 15 amp receptacle, and said it will be ok. I told him I thought I read something that you can't do that. He said they do it all the time. So I researched it again and it's ok if other circuits are on the 20 amp breaker,but for a dedicated line it has to be a 20 amp receptacle.  Thank God I haven't pluded anything into it yet. Ordered a 20 amp Hospital grade red receptacle.
