VIII. METERING EQUIPMENT 800. GENERAL The customer shall furnish and install Company-approved meter mounting devices, including outdoor enclosures, instrument transformer cabinets and indoor test or connection block cabinets in accordance with the requirements in this handbook and NEC Article 312. Refer to the "Supplement" for meter mounting equipment requirements and options (see inside back cover of this handbook). All such enclosures must be sealable with padlock type seals and such seals shall be removed only by qualified Company employees. All metallic equipment used for metering purposes shall be properly bonded and grounded as required by Section VII and the applicable Illustration in Section XII of this handbook, and NEC Article 250. For services with instrument transformer-rated metering, an overall meter enclosure as approved by the Company is generally required. See Illustrations No.s 14, 15, 16 and 17 in Section XII. A meter socket (enclosure) shall be permanently and solidly mounted before the meter will be installed. All outside meter enclosures must be secured by screws, #12 minimum, which are stainless steel or zinc or cadmium coated (no washers allowed). Wherever a meter enclosure is mounted on siding (no backboard), use of screws that accommodate a Phillips and/or slotted style screwdriver is requested. Self-contained meter sockets attached to a building shall not be secured such that cables will prevent subsequent access to the mounting screws. This requirement is to allow for future “floating” of the meter socket. The Company will furnish and install all meters. When required, current transformers (CTs), voltage transformers (VTs), 51 51
52 test switches and control cable for installation in the customer's approved equipment will be furnished by the Company. In accordance with MPUC's Chapter 320, "whenever practicable, all electricity sold (delivered) to one customer on one billing will be measured (metered) at one point." Furthermore, the metering should be located at, or near, the point of delivery and at delivery voltage whenever it is practicable to do so. For any alternative arrangements, contact the Company's Marketing & Sales (M&S) Department. The customer shall make reasonable effort to separate residential and non-residential use for metering purposes. 801. METERING MULTI-TENANT BUILDINGS A. RESIDENTIAL SERVICE As a general rule, in accordance with the Public Utility Regulatory Policies Act of 1978 (PURPA), each dwelling unit in a building that contains more than one residential dwelling unit will be separately metered. Inquiries regarding application of/exception to, this rule should be referred to the Company's Marketing & Sales (M&S) Department. If the building is master metered, then for residential rate application, there shall be no three-phase load on the residential master meter; however, the service to the building and the residential master meter itself may be three-phase. B. GENERAL (NON-RESIDENTIAL) SERVICE As a general rule, in accordance with PURPA, each separately leased or owned unit in a building that contains more than one non-residential (commercial) unit will be separately 52
