Original Version

Rule 56.7-C

56.7-C.    Truss Guys

An insulator shall be installed in each truss guy which is required to be sectionalized by Rule 56.6-A, so that such insulator is located not less than 8 feet above the ground and not less than 8 feet below the level of the lowest supply conductor passing within 8 feet of the guy (see App. G, Fig. 51).  These requirements can normally be met by insulation at one portion; however, in certain unusual conditions the two 8-foot distances may overlap, in which case insulation will be necessary at two positions.

An insulator shall be installed in each truss guy which is required to be sectionalized by Rule 56.6-A, so that such insulator is located not less than 8 feet above the ground and not less than 8 feet below 8 feet or more above the ground and 8 feet of more the level of the lowest supply conductor passing within 8 feet of the guy (see App. G, Fig. 51 Fig. 56-10).  These requirements can normally be met by insulation at one portion; however, in certain unusual conditions the two 8-foot distances may overlap, in which case insulation will be necessary at two positions.
