Rationale

Induction Hazards: Electric fields and magnetic fields are developed and always present whenever energized AC overhead transmission systems are present. Electric fields and magnetic fields generated by these energized systems can “induce” a charge into nearby de-energized conductors and cables through what is called “capacitive coupling” and “electromagnetic coupling.” The intensity of the electric fields and magnetic fields is directly related to energized system’s voltage level, current flow, and the proximity to the energized system. It is often thought that workers are safe to contact a de-energized conductor or cable, located in the vicinity of an energized system, if the de-energized conductor or cable has been grounded. But, in fact the grounding process of a de-energized conductor or cable may increase the hazard to workers if grounding procedures are applied incorrectly.
