Co-ordinated protection for open-wire joint use -- Ontario tests

WHEN POLES are jointly used by power and communication utilities, or the two types of plant are on separate pole lines but are in situations of close proximity, the possibility of accidental contact between the two types of plant must be recognized. The first line of defense against such occurrences is to minimize the probability of contact by means of adequate construction and clearance standards, as covered by the National Electrical Safety Code in the United States or the Canadian Electrical Code in Canada.
