SECTION 1 GENERAL INFORMATION
“Information and requirements for electric service” is issued as a means toward better communication between customers, architects, contractors and engineers. The requirements contained herein are supplementary to MMLD’s schedule of rates and their terms and conditions filed from time to time with the state departments of public utilities.
SECTION 2 VOLTAGE
The information contained herein applies primarily to electric service requirements for installations at voltages not exceeding 600 volts. Service requirements above 600 volts are subject to special negotiations between the Customer and MMLD.
SECTION 3 ENFORCEMENT OF RULES
All wiring and equipment intended for connection to the mains of MMLD shall be in accordance with the requirements of the local municipal inspection authority, the National Electrical Code and MMLD. No service connection will be made until approval is received from the local municipal authority (Wire Inspector). All connections to MMLD’s system shall be designed, installed and operated in a manner that will not cause undue disturbance to other customers. The Customer shall not continue to operate any equipment or apparatus that adversely affects the service to other Customers.
SECTION 4 APPLICATION FOR NEW OR ADDITIONAL SERVICE
Application for new service or additional service or changes in the present service be made as early as possible so that engineering details and work schedules can be planned so that construction for the new or changed facilities may be completed on the date required.
SECTION 5 ADDITIONAL LOADS
MMLD facilities are normally designed to meet Customer initial requirements at the time service is installed. When additional load is contemplated MMLD should be notified as early as possible so that proper provision can be made to furnish the additional service.
SECTION 6 RELOCATION OR ALTERATION OF SERVICE
Whenever changes are made in existing service installations involving relocation, replacement, or additions, the entire service installation shall to the extent practical, be rebuilt to present requirements. The service changes must be approved by the Municipal Inspector before MMLD will connect to the Customer’s equipment. Contractors must check with MMLD and the Wire Inspector before bidding on service installations.
SECTION 7 INSPECTION CERTIFICATES
MMLD is not allowed to energize wiring until certificates of approval have been issued or specific verbal approval is granted by the Municipal Inspector.
SECTION 8 TEMPORARY SERVICE
“Temporary Service” is any service such as a construction project, temporary display, etc. which is not expected to continue in use for a period long enough to justify a permanent service installation. For Temporary Service, the Customer will pay in advance the fee for installation and removal of the connection equipment. Temporary Service equipment supplied by the Customer must be inspected and approved by the Municipal Inspector before MMLD will energize the service.
SECTION 9 FINAL CONNECTIONS
MMLD will connect Customers wiring to MMLD facilities for permanent or temporary services and will not permit or tolerate unauthorized persons to connect to MMLD conductors or equipment.
SECTION 10 CUSTOMERS STANDBY GENERATOR
Where the Customer installs a standby generator for supplying all or part of the load in the event of an interruption in supply of MMLD service, wiring shall be arranged so that no electrical connection can occur between MMLD service and the Customers other source of electrical supply. This will require installation of a double throw switch or an equivalent arrangement approved by MMLD.
SECTION 11 DEFINITIONS
Service Drop: Overhead service conductors between nearest pole and location of attachment to building.
Dead End: Attachment on building supporting the service drop.
Drip Loop: Conductors owned by the Customer providing connection space to attach or connect to the service drop.

SECTION 12 INSTALLATION OF SERVICE
Overhead service not of a temporary nature will be installed without charge, with certain exceptions as provided in SECTION 15A and provided pole locations and or right of way can be obtained.
SECTION 13 MAXIMUM SPAN OF WIRES
The maximum single span distance MMLD will run its overhead service drop conductors to the point of dead end on a customer building is 120 feet. Building heights, large conductors, street and driveway crossing, may reduce the maximum permissible spans.
SECTION 14 POINT OF ATTACHMENT (DEAD END)
The service drop will be attached to the building or other structure at a suitable point determined by MMLD which is not less than ten feet, nor more than 25 feet above finished grade level. The following clearances are a requirement for service drop cable at its closest point to level finished grade.
10 feet from finished grade, sidewalks or any platform or projection from which conductors might be reached.
12 feet over residential driveways.
15 feet over commercial areas, parking lots or other areas subject to truck traffic.
18 feet over public streets, alleys, roads and driveways on other than residential property.
