I am putting the new electric, phone lines and television cable into a
new addition. I was wondering if the phone line or TV cable touches the
electric wires when they criss cross each other will the electric wire
cause any interferance in either the phone line or TV?

If this can cause interferance, what would be the minimum distance
between those lines to be sure one does not cause a problem with the
other.

Thanks, David

There is a lot of urbal legend about this but the short answer is you
won't have a problem with coax or twisted pair. If you have the old
style untwisted phone wire and you ran next to the power for a long
distance you might pick up some hum.
If you think about it, your phone runs next to power lines for miles
... but the wire on the pole is twisted

Not where I live. The power lines run at the top of the pole, the phone
and cable lines run across the middle.

It also matters whats on the end of the power lines. A noisy appliance
like an old motor could be a problem. But phone lines are really not
that low of a voltage that I would worry about that.
