Here is a reference from the TIE/EIA-570-A Residential Telecommunication
Cabling Standard:

"8.1 3.1 Separation distance from electrical power
Separation of telecommunications cable with respect to electrical power
conductors shall meet applicable electrical codes. Additionally, when
telecommunications cable containing metallic elements (e.g., UTP, coaxial
cable) is placed alongside unshielded electrical power conductors inside
wall space or ceiling space, it shall have a minimum separation of 50.4 mm
Q in) from power wire."

Also your local codes (possibly NEC) may have other requirements. You can
check with your building/electrical inspector or the AHJ (Authority Having
Jurisdiction).

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
