I am looking for a good rule of thumb for the separation between 4-20mA signals and 480V wiring. I need to run both cables overhead on poles, both will be armored, shielded cable. The NEC gives minimum (safety) specs, I want to make sure there is no crosstalk. Although the conductors are running parallel to eachother, surely there is a distance beyond which crosstalk is impossible.
Thanks,
