1. Electrical wire versus speaker wire and other low voltage wiring
I hesitate to even ask this as I've poured through this and other newsgroups
and see that there has been significant discussion on this topic. But I
swear I can't get to the bottom line.
Consensus seems to be that these wires should not be run next to each other.
Where this unavoidable, some separation should be maintained (I've seen I
think 6" to 18" quoted). Where they must cross, try to do so at a 90 deg
The reasons for doing this seem to be a little more up for debate (again,
this is just my interpretation of what I'm reading). For instance, with
audio, while in theory, it sounds like there could be some degradation of
sound quality as a result of proximity to HV wires, it sounds like it would
probably be so small that no one would really notice.
It sounds like there is also a safety concern (perhaps the bigger issue). A
short or heat from the HV wire could damage equipment or people at the other
end of the LV wires. Is this the bigger issue?
Is this in fact a code violation? It seems clear that running these wires
in the same conduit is a violation. What if there is no conduit involved?
What if they are just laying on top of each other running across the joists
in the attic? What about going through the same hole in a stud? Is that a
code violation and/or a safety hazard?
Here's the reality of my situation. I'm having a house built and the
electrical wiring is in place. The audio wiring (whole house distribution
with speaker wire and CAT5 home run to the media center) was completed late
last week. No conduits involved at all. There are a few places where the
speaker wire and CAT5 are running alongside the electrical wire, mostly up
in the attic. There are many more places where they share the same hole
through a stud or joist.
Do I have a problem here? If so, is this an issue of signal degradation, a
safety hazard, or a code violation? Or any or all of the above? I believe
that my house has already passed the electrical inspection, done prior to
the audio wiring being installed. Not that passing the inspection is my
ultimate objective. I don't want to do anything stupid or create some sort
Thanks for the feedback and forgive me if I should have been able to figure
this out from previous posts.
