Yes! It isn't legal anywhere I have ever been. It is dangerous everywhere
you find it done.

>if so how far would they need to be separated?

There are rules of thumb about that. It doesn't really apply in your
situation, but the idea is to avoid an inductance in the low voltage cable.
If low voltage wires have to "cross" high voltage cables it should be
infrequent and at 90 degree angles.

If the CAT 5 is going to be certified it will never make it being run they
way you're talking about. The telephones may end up with a nasty A/C hum as
well.

NO WAY!
