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.

If you're going to the trouble and expense of dedicated lines then you might want to first check out the home wiring cable from Virtual Dynamics Home Wiring Products

Since you have such short runs, you might want to think about making your own cable. Using two individual runs of solid core 10 gauge, simply twist them together i.e. make a twisted pair out of them. The twists don't have to be consistently spaced, but should be done at a rate of appr 3 - 4 turns per foot. This will be used for the hot and the neutral. The ground wire can be run individually outside of the twisted pair.

One suggestion here. If your runs are going to be 20 foot, start off with 25 - 28 foot of wire or so. You WILL lose length as the wire is twisted. For your own sanity, it is best to cut individual runs and work with the shortest lengths possible. That is, don't try and twist 100 ft of cabling together and then cut to length. Having another person to hold the far end and rotate it accordingly can make things go MUCH quicker and easier. Sean

Never mind mind making your own wire. You must meet bldg. codes. In case of fire, failure to do so might result in your liability. The insur. co. won`t pay a red cent.
Thank you all for the suggestions; much appreciated. Please keep them coming, and I will keep you posted as to my choices and results.

Making your own wire from two CL3 rated runs of 10AWG should meet code. As long as you have the ability to properly terminate and attach both ends it should be no problem.
Now the fact that you are making your own Romex is another discussion entirely. That may not meet teh standards for good mental health.
