Original Version

Rule 70

70    General

The following rules cover certain special details for the construction of Class T circuits, together with their supporting messengers, span wires and appurtenances.  These rules are in many cases supplemental to the rules for supply lines in general (class T circuits being be definition supply lines), which general rules, including construction details of Section V, must be observed, except where clearly inapplicable or where specifically modified herein.

When the use of a special type of construction appears desirable or is necessary, and these rules are not clearly applicable thereto, the Commission will consider the application of a trolley system for such modification or amplification of these rules as shall be deemed necessary to apply to such case or special construction (see Rules 15 and 16)
