§ 110_110.15

Revise this section as follows:

San Francisco has deleted language from the 2010 California Electrical Code from this paragraph.110.15 High-Leg Marking. On a 4-wire, delta-connected system where the midpoint of one phase winding is grounded, only the conductor or busbar having the higher phase voltage to ground shall be durably and permanently marked by an outer finish that is purple in color or by other effective means. Such identification shall be placed at each point on the system where a connection is made if the grounded conductor is also present. Identification of ungrounded feeder conductors shall comply with Section 210-5(C).
