A. In an area served by overhead lines, when a customer desires that the service shall run underground from the pole to the building, the owner shall install the requisite service equipment.  The Electrical Inspector shall be consulted as to the advisability of such a service and shall specify the meter location and the pole from which the service shall be run.  Either conductor suitable for underground installations in conduit or other cable approved for the purpose, installed in accordance with the utility's specifications, shall be used.  Where the conduit enters the ground at the pole or building, it should be enclosed in concrete to a depth of eighteen (18) inches.  Such service shall be not less than three (3) conductors No. 4 and as much larger as the load requires.  Such underground service shall be installed entirely at the customer's expense and maintained by the customer.

B.    If at any time the Electric Department needs to replace a pole supporting an underground service connection, installed as provided in Subsection A, the customer shall be notified of the time, and he shall have his electricians on hand to take care of the service while pole replacement is being made.
