Urgent help: fuse breaker box for dedicated line?

Hi,
I've looked for a fuse breaker box for my dedicated line at Home Depot, but I can not find the one that use 120V. Home Depot has only a few types of fuse breaker box, but none of them use 120V (240V only). Here are my questions
1/ Can I use 240V box for 120V? I asked the guy in store and he told me that I may use it but the current will be double (he's not sure about it).
2/ The one that I've looked for is 240V/60A with 3 slots to put fuse. Does it matter for double the current in case I use 240V box for 120V if I use only 20A fuse?
3/ The maximum slots in breaker box that I found is three. Do they make four slots? Where can I find them?
4/ I see JPSlabs.com have special wire for dedicated line for $3.5/foot. Is it good compare to Romex or THINN wires?
I'm interested in JPS wire because I need only 20' for three outlets from the sub panel.
Thank you very much.

In all seriousnesss with the kinds of questions you are asking you need to hire an electrician. I would hate to see you destroy your equipment or worse burn up your living quarters. At least go to an Electrical Supply house near you and ask questions. Stay away from Home Depot or Lowes. They are good places when you know what you want but when you have to ask the kinds of questions you are asking they may not be the best source. Just my two cents.

I ran the wiring for my dedicated lines back to where I wanted my circuit box then hired a licensed electrician to install the box and breakers. This saved me some money on the straight forward stuff and insured proper installation of the electrical connections, also most electricians will use better quality parts than those available at "home centers".

Hi,
I'm in process of building a listening room, and the contractor will do the dedicated line for me. However, I have to supply all the parts, and I want all the parts will be ready before the contruction starting.
I want to buy all the parts now just because I'm off for the whole week. I'll be busy next week and I don't want to wait for the contractor until next Monday.
I already have dedicated lines in my old room, so I know little about it except for the fuse breaker box, and I don't know where the last electrician bought it.
Thanks!

When asking an electrician for dedicated lines, I advise you to include overload protection as well in the case lightning should strike in the direct vicinity of your home(s). Small extra investment, large amout of security.

I'll second the need for an electrician. Your 240v sub panel will provide 120v. Just use a 1 pole(slot) breaker. 240v would require a two pole breaker. Sounds to me as if your using a fuse box, in that case your hot leg off the fuse and your neutral would comprise the circuit, with the ground for safety purposes. If you double the voltage you cut the current in half, that is why transmission lines aren't the diameter of sewer pipes. If your only running your audio equipment one circuit will suffice. You should pull romex wire 12 guage 3 conductor or 12/3. Thinn is stranded wire with an insulation that is oil resistant. Email me if you have any other questions. Mdoughty@nycap.rr.com
