4. (d) Location of meters.

   1. (1) Meters and service switches in conjunction with the meter shall be installed in accordance with the latest revision of American National Standards Institute (ANSI), Incorporated, Standard C12 (American National Code for Electricity Metering), or other standards as may be prescribed by the commission, and will be readily accessible for reading, testing, and inspection, where such activities will cause minimum interference and inconvenience to the customer.

   2. (2) Customer shall provide, without cost to the electric utility, at a suitable and easily accessible location:

(3) All meters installed after the effective date of these rules shall be located as set forth in this section, provided that, where installations are made to replace meters removed from service, this section shall not operate to require any change in meter locations which were established prior to the effective date of these rules, unless the electric utility finds that the old location is no longer suitable or proper, or the customer desires that the location be changed.
   4. (4) Where the meter location on the customer's premises is changed at the request of the customer, or due to alterations on the customer's premises, the customer shall provide and have installed at his expense, all wiring and equipment necessary for relocating the meter.

5. (e) Accuracy requirements.

   1. (1) No meter that violates the test calibration limits as set by the American National Standards Institute, Incorporated, shall be placed in service or left in service. Whenever on installation, periodic, or other tests, a meter is found to violate these limits, it shall be adjusted.
   2. (2) Meters shall be adjusted as closely as practicable to the condition of zero error.
