General Networking Question

Hope someone here can answer my question.

Do I have to worry about electrical interference if I run my networking
cable next to household electrical lines? In my basement, there are a couple
of places that 1" holes have been drilled in the floor joists and the
electrical wires ran through them. If I ran my network cable in that same
path, would I experience interference?

Thanks,
Sam

It's possible it would affect it. 10/100-base-T cables are
differential pairs and as such have a high degree of common-mode noise
rejection. If you minimize the running distance that the cables are
close to each other, it probably won't affect it much. Shorter runs
would be affected less than longer ones. Try it and see.

I'd suggest posting the question to the folks at comp.dcom.cabling. Lots of
knowledgeable people over there.

As to an answer, many jurisdictions have codes explicitly against this
practice. The more stricter codes define a minimum distance between low
voltage wiring (network and phone) from electrical wiring. In addition,
some codes require that low voltage cross standard electrical lines at a 90
degree angle.

In my experience that's a bit over kill, but it's certainly food for thought
when running you wires.
