I have a computerized energy management system (open motherboards located in a NEMA 1 panel. 120 Volt power, feeds class 2 transformers that supply computer and field devices attached to this computer (transducers and such). Power wiring is in close proximity to class 2 cables. Where a class 2 cable (twisted pair conductors encased in plastic wrap with class 2 labeling on it) is in tight contact with 120 volt power conductors, is this permitted. I believe minimum conductor to conductor distance requirements is 2 inches, but what about cable to conductor?
