I'm having my dedicated lines put in tomorrow. I'm doing one 15amp and one 20amp and have purchased audio-grade outlets.

Can I ask what I should ask the electrician to do specifically? Here's what I plan on telling him:

1. Use 12ga. armored cable (is any 12ga OK)? He told me that the ground in the house is 14ga, so having 12ga shouldn't make a difference at all - but he'll certainly use the grade I want. Any reason to go to 10ga?

2. A continuous line

3. Make sure the house ground is secure/clean/re-apply as necessary.

Is there anything else I should do? Should I get him to solder to the outlet, or is it best I do that on my own after he's gone? Sorry to hijack the post.

Thanks

a. continuous run...no splicing

b. make sure he runs 1 hot, 1 neutral and 1 insulated equipment grounding conductor PER circuit. No shared neutral.

c. consider using plastic boxes instead of metal. Search the archives under Al Sekela's name with keyward "plastic box" "dedicated circuit"

d. In the panel, place both dedicated circuits on the SAME leg but on the OPPOSITE leg of major applicances (washer/dryer, fridge, dimmer lighting, etc.). See if he can re-organize the panel to achieve this.

e. I had trouble finding 10awg armored cable. Some rec 10awg, but 12awg is widely used and made an audible improvement for me.
You might consider improving the entire system's ground by installing another pair... - jeffreybehr 11:05:47 06/11/07 (0)
...of 8' ground stakes near the main panel and running a new 4g. ground wire to them. Or, if the existing ground stakes are already near the panel, add a new pair farther away. AFAIK, there's no problem associated with IMPROVING the ground.

If you'll be feeding more than one duplex outlet, be sure NOT to break the wires at the 1st outlet. IOW, the continuous run should continue to the last outlet on that line.

Most of the archieves mention 10g wire for decicated circuits. If your going to the trouble already...plus it will keep you thinking "maybe i should of put in 10g), and why not use two 20amps circuits. Just a couple of thoughts. Good luck
