Installing dedicated lines. Which cable to use?


Hi guys

I'm having some dedicated lines put in. I've already purchased some Porter Ports (what a great guy that Albert P.!), and have a couple of questions concerning which cable to use. I want to use 10-2 solid core, but am confused about a couple of things:

-the runs from the breaker box will be relatively short (15-20 feet). Should I use shielded Romex or unshielded? I do have some problems with noise (hum, buzz)in my setup when using unshielded interconnects (Nordost). I am told that unshielded sounds better but is noisier. Experiences?

-I am having trouble locating brand name Romex. The local HD and Lowe's don't carry it, but do have a Romex-like 10-2 copper wire. Is real Romex worth the search? Lots of references in the archives to Romex from HD. What gives? Is the name Romex used generically to mean any similar cable? What is a good source for real Romex?

Thanks in advance and any other suggestions or tips would be greatly appreciated.

Hi there I got a real kick reading all these threads.12-2 is rated for a 20 amp circuit. 10-2 for 30amp. The line will run cooler with 10-2 very very difficult to work with! Romex is national code, and refeers to the insulating jacket. Your
other code approved option would be THNN and conduit. More importantly than your wire options should be the service panel itself. Other than Square D QO line ,and another midwest company all panel companies do not use a solid copper buss bar! Good Luck!!
