No, It doesn't work that way. Just my 2 cents as electrical engineer for over 30 years. It's all good. :)
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

I rewired my home entertainment system when I saw a good deal on a 125’ spool of 8 gauge wire. There are NO splices along the line and it terminates in a 30 amp plug that feeds the industrial surge protector for equipment in the entertainment center and two hospital grade outlets just outside the center. (Again, all a continuous run without splices.) The "power consumers" in the center include a Yamaha RX-Z9 Receiver (1,200 watts rated input), a Crown PSA-2XH (eXtended Headroom), bridged, making about 800 watts into a 12 ohm load (20 amp rated input), and a Sunfire Signature sub (2,500 watt disclamer) The line got it’s own 20 amp breaker, and I even put a big ferrite bead on the line. The Yamaha SACD became less grainy, but I didn’t really notice any audible difference in the Oppo95, which uses a better power supply.

@invalid , the “large” short burst of current is feed by the capacitors. Most amps have an AC line fuse of less than 15amps, therefore, the fuse will blow before the breaker (assuming a 15 amp breaker) |

@speelerr I must be misunderstanding your post, most breakers have a trip curve chart, a 15 amp circuit breaker will not trip at 15 amps for a certain time period, which means your equipment could actually draw many times that 15 amps and not trip the breaker if it's for a very short duration of time and it can cause voltage drop.
