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

The electrical engineer went to school and studied electric. I would follow his recommendation. I’m a builder and I recommend the same. 3 dedicated outlets. Pretty cut and dry. 

First, a dedicated circuit is always preferable. 

Second, no, your loads are absolutely not connected in series. Loads are connected across the hot and neutral, in parallel.

Third, yeah, probably 3 dedicated circuits, all pulled from the same leg (same side of the breaker box) to minimize potential ground loops and different ground impedances.

Connecting two 20 amp circuits to the same leg of a power source is not recommended as it can overload that single leg, potentially causing issues like uneven power distribution, tripped breakers, and potential damage to your electrical system; it's best to spread the load across both legs of the power supply by connecting circuits to different legs whenever possible
