Dedicated line help

Finally getting the dedicated line I've always wanted, but had a few questions on how it should be done for best results. My electrician is kinda young and is not an audiophile (the flipside is he's only charging 75 bucks to do it), so I'm relying on you guys for the details.

Some general info in case it's helpful: The system is in the basement and in the same room as the circuit box about 30 feet away. The wire will be fished behind the walls that fortunately have a few access panels between the box and my system, and there is no insulation between the wall and the foundation -- just some heat pipes (steam heat).

Questions:

Is 20amp strongly preferable over 15amp line or does it not matter that much? I'm currently running a 125wpc push/pull solid state amp but may very well run something like a 100wpc class A ss amp in the future, if this makes a difference.

I'm going to purchase a Porter Port, but is there certain type/brand of wire that should be used from the circuit box to the Port or will the standard stuff do fine?

Should I have him run 2 lines -- one for analog and one for digital, or is there another way to separate these guys (or is it sufficient just to do this at the power conditioner, which I don't have yet)?

Anything this guy could do wrong that could cause problems or create a fire hazard?

Any other tips you guys have either on the installation or equipment would be most appreciated. THANKS FOR ANY THOUGHTS/HELP.

Just did it last month with 4 lines and a separate subpanel with Romex wires and Furutech ports.

I live 4 blocks from powerlines (not sure good or bad) and berfore installation, the room had pseudo dedicated lines except for lightings

Improvement was not jaw dropping at any single aspect but there is noticeable improvement on almost all aspect. Before installation, I had to run preamps, phono off a conditioner; otherwire there is lost of subtle detail, soundstaging and texture. After the dedicated AC installation, the difference with and without AC conditioner is insignificant.

Why do folks suggest 2 dedicated lines 1 for analog and 1 for digital? Why not one? Using a power strip for added outlets from the dedicated line to plug all your gear into.

Digital adds noise to the AC line.

My dedicated lines are being run as I type this. Thanks for all the advice. My electrician is running the lines on the same leg and not sharing a neutral bus, which I don't know if he would've done had it not been for your advice. I ended up running two lines (12/2 Romex) one of which I'll plug in my amp and pre, and my DAC and transport will go in the other. I know I should've probably run more, but this seemed like a good start and since a power conditioner or surge protector is in my future this may end up being enough.

So now I have my old line, one dedicated line with a Porter port and one dedicated line with an average recepticle (I'll upgrade that to a Porter port at some point). This should make for some interesting comparisons and I'll report back on the differences in case anyone might be interested.
