This section is included in your selections.

A. No motor shall be allowed to start which causes interference with other customers. Maximum single phase allowable is five (5) HP by special permission, otherwise three (3) HP. Three (3) phase motors twenty (20) HP and larger shall have reduced voltage starting where customers other than the applicant are served from the same transformer bank. Each customer shall review the motor starting requirements of customer’s equipment when it may interfere with the customer’s own electric service. See Table #1 for other allowable motor starting conditions.

B. Other devices which cause unusual fluctuation such as X-ray apparatus, hoists, furnaces, electric heat, must be limited to reasonable levels on request of the City.

C. The customer shall provide circuit protective devices or fuses at customer’s service entrance or cable attachment to protect the power company equipment from any faults.

D. The location of the overhead service, where applicable, shall be on that portion of the building that can be served from the City’s facilities at a minimum of cost. Clearances shall be in accordance with the National Electrical Safety Code, latest edition, and in general the point of attachment and line routing shall be not less than twelve (12) feet above the finished grade. Across roadways greater heights are required. Confer with the City staff where there may be unusual circumstances. Additional poles will not be installed to render service at the rear or in an inaccessible point of the building, except at customer’s cost. Minimum metal raceway for overhead or underground service entrance shall be two-inch (2") rigid galvanized steel conduit securely fastened and to give a minimum of three feet above inaccessible roofs or other roofs may require additional clearance.

E. The customer shall provide protective devices for the customer’s equipment to protect against single phasing and high and low voltage conditions. Three (3) phase motors shall have protection in all three (3) legs. Wiring facilities on the customer’s premises shall be kept at customer’s expense.

F. The City Electric Department may require the customer to provide, at the customer’s expense, equipment to reduce the lagging or leading reactive requirements (KVAR) of the customer’s equipment so that the ratio of total KW to total KVA (volts times amperes times square root of three (3) for three (3) phase is not less than eighty-five percent (85%), commonly known as power factor. This is not more than sixty percent (60%) reactive power to one hundred percent (100%) true power. The City reserves the right to bill twenty-five cents (25¢) per KVA of excess reactive demand per month if the customer fails to reduce the reactive demand to the limits above.

G. The customer shall notify the City when adding additional load which may affect the ability of the City to provide adequate service with existing lines and equipment.

H. The City reserves the right to refuse service to loads of a character that may seriously impair service to any other customers unless the customer agrees to provide, at customer’s expense, suitable equipment to reasonably limit such fluctuations, as in the case of hoist or elevator motors, welders, furnaces, compressors and other installations of like character, where the use of electricity is intermittent or subject to violent fluctuations.
