Circuit Status

I was looking to install dedicated circuits - one each to two, duplex receptacles that are located just behind my components (the components are positioned along a solid shelf that is built onto the wall that the duplexes are located on; the duplexes being right behind the components). To that I checked out the current status of the circuit . . . .

I have identified that these two receptacles are the only objects on a circuit running from a subpanel located below and approximately 15 ft from the receptacles. The cable feeding the receptacles is 14/2 Trendex. The cable feeding the subpanel is 8/3 Trendex; the subpanel located approximately 60 ft from the main panel and point of delivery of service into the residence. I replaced the receptacles a few years back with 8200HICN series Hubble. I don't remember offhand how the receptacles were wired, but the electrician did use plastic wire connectors to feed off separate wires to the first receptacle, extending another set of wires off the connectors to the second receptacle. I wired the same. Plastic receptacle boxes at each. Solid copper ground wire from receptacle to connector.

Not knowing all the answers to this, I leave the actual work of wiring to electricians. But I would like to know just what should be upgraded in this circuit. My guesses with limited knowledge: 12 or 10 ga cable to the receptacles, perhaps better receptacles, optimal placement of receptacle cable at subpanel (although it is positioned with nothing opposite it). Am also wondering if indeed dedicated circuits to each is any better than having both (but just the two receptacles) on a single circuit.

Sounds naive is is somewhat naive. Never thought much about AC supply until recently. Poured through searches and came across quite a bit. But I suspect that to a degree, the existing circuit is close to what should be.

Terra, it appears that your two outlets are daisy chained, and thus you have in effect only 1 dedicated circuit. That circuit is a perfectly valid dedicated one since it comes directly from a subpanel.

You need to determine the total steady state current draw when all your components are on but not playing music, and then the peak draw when the amp is maxed out. You will use this to help determine if more circuits are needed, and if you need to go to 20 amp. Since you runs are relatively short, that may not be necessary.

I would suggest a minimum of two circuits, although some run several just to be conservative. You might be able to keep the one you have and just add another. Are there any other circuits in that subpanel?
