15A vs. 20A power cord questions

I installed two dedicated circuits using #10-2 with ground MN-B cable.

One for digital and the other for analog.

It’s you call if you want to spend the extra money for the other line.

Because you are using #10 branch circuit wiring you should not have any fluctuating VD, voltage drop, problems playing moderate to loud dynamic music through your amp. And because all your equipment is analog one dedicated circuit is probably all you will ever need.

If you think there is a chance some time down the road you may add some digital equipment to the mix you could have the electrician install another cable now for future to a separate cut in wall box. Just have him put a blank cover plate on it for now. At the electrical panel he could terminate the neutral and equipment ground wires and tape off the end of the black hot wire for the future if you decided to use it. Extra price? Material plus just a little more labor cost. Definitely cheaper now than later. Future hook up cost? One hour labor rate, should cover it.

Who says an old dog can't learn new tricks.

Thank you for enlightening me. No isolated ground rod.

I have two wall receptacles for him to install. Should each one be on a different breaker? Do you run the 10-2AWG to each wall receptacle?

What were you trying to achieve by doing this? What have you achieved by doing this?

It’s up to you how many dedicated branch circuits you want to have installed for your audio equipment.

You can have just one installed and have the electrician install both duplex receptacles on the single dedicated branch circuit. If you go this route I recommend you have the electrician install a separate wall box for each duplex receptacle even though he will tell you it is cheaper to install both of them in a 2 gang box putting the duplexes side by side.

Problem with the duplex receptacles installed in a 2 gang box side by side is if you have any equipment or may have in the future that uses a wall wart. Most wall warts when plugged in covers part of the receptacle of the duplex receptacle next to it.

Something else to think about is the location of the wall receptacles.

Do you want them hidden out of sight? Problem with that they are a pain to unplug equipment from during a lightning storm, and even a bigger pain trying to plug them back in. Same problems if you want to experiment with different aftermarket power cords.

More than one dedicated branch circuit?

You said you all ready have 2 Furutech GTX-D 20A duplex receptacles.

Gold $234.99 each.

Rhodium $244.99 each.

And from what I have read about the amount of burn-in time required for the Rhodium receptacles a pre cooked duplex receptacle runs $264.99 each.

So the only additional cost for another dedicated branch circuit is the cost of the NM-B cable, the additional 20 amp circuit breaker, and a little more labor. As for the labor the only additional time involved is installing the NM-B cable, installing the 20 amp circuit breaker, and terminating the hot, neutral, and equipment ground, at the electrical panel.

Sounds like a no brainer to me. Install two dedicated circuits. One for each duplex receptacle. Someday you might add some digital equipment to your audio system.
