Requirements for Underground Electrical Supply

General Order 128

The purpose of GO 128, in effect since 1967, is to formulate uniform requirements for underground electrical supply and communication systems to provide adequate service and secure safety to all persons engaged in the construction, maintenance, operation or use of underground systems, as well as to the general public. Like GO 95, GO 128 sets both construction and maintenance standards. (See § 12.2.)
