Electrical Question from Ronald about the separation of communications and power cables

Dave’s Reply:
Thanks for your electrical question Ronald. Great Question. There should be a minimum of 12 inches separation between communications cables and power cables. Crossing at 90 degrees is ok when necessary. If the communications cable is not shielded then it would be best to be further away to avoid emf and noise disturbances.
