YOu guys are right.

Carry on!

THe line will have to be serviced with a 15A breaker to use 15A outlets.
Edit. Sorry Guys, I was wrong,

I thought the same thing Martin! It is so unintuitive! Should put it in the "Strange, but True!" section...  :)

If anyone needs something a bit more substantial than average for your system, just let me know  :lol:  Thread reminded me of it for some reason...

Thanks for the tips, fellas.

The electrician would prefer to put the subpanel closest to the main panel but this is is at the far end of the basement from where the system lives above. I would prefer to have the subpanel under the system, requiring a long (60-70') run of the 240 V (or is it 220V?) line from the main panel to the subpanel.

For such long run, what gauge wire should I use?  I assume copper only. The really fat copper gets pricey tho.

A long run to the subpanel = short runs to the system, which I'd prefer. I could then perhaps spring for the JPS in-wall.

Thanks again,

-Mike

The subpanel under your system is preferable in minimizing potential ground loop issues. Are you planning on using both legs of the 240 (120vac-120vac) from the subpanel?, perhaps one leg for your AV equipment and the other leg for other uses to keep external noise out of your audio. If you're only going to use the one leg, just for powering your system, if within code, you could save by only running 1 of the 2 120vac legs and be sure to have the subpanel labeled as such so the next electrician dealing with it isn't totally flummoxed. 6 gauge solid core is indeed expensive. Lastly, I run my system off a single 20 amp circuit. No subpanels required, minimal potential for loops. But I also use multiple filter power conditioning that isolates components from each other.

I'm looking forward to your report(s) on how this investment in resources effect your system.

Regards,
Paul

Charles,
Are you implicitly chastising me for being  a total prick on the other board? :rofl: If so, I admire your perceptiveness.

Have a great holiday!
