17 AAC 90.430 - Construction and design

(a) A meter must consist of materials, design, and construction to assure its accuracy under normal service conditions.

(b) The cover of a meter must be strong enough to withstand ordinary usage. It must be dustproof and designed so that access to the interior requires the destruction of a seal.

(c) The ratio of the rated load torque to the friction at the speed corresponding to the rated load must be high, to minimize the possibility of a change in the accuracy of the meter due to friction.

(d) A meter must be designed so that the cover and terminal chamber can be securely sealed. Sealing arrangements must be designed so that authorized personnel may have convenient access to the meter for tests, adjustments, and maintenance. A security seal must be affixed to a meter in commercial use.

(e) The terminals of a meter must be arranged to minimize the possibility of short circuits in removing or replacing the cover, making connections, and adjusting the meter.

(f) A meter must easily allow the determination of the number of kilowatt hours registered by the meter. If the reading of a meter requires the use of a constant to calculate the kilowatt hours consumed, the proper constant to be applied must be prominently marked on the face of the meter.
