Wisconsin Administrative Code › Public Service Commission › Chapter PSC 113 - Service Rules For Electrical Utilities › Subchapter VIII - General Customer Metering and Meter Accuracy › Section PSC 113.0809 - Installation of metering equipment

Current through June 24, 2024
(1) The customer or
				the customer's agent should confer with the utility as one of the first steps
				in planning an electrical installation. The watthour meter should be located
				where it will be readily accessible for reading, testing and repairs and where
				it will not be subjected to adverse operating conditions or cause
				inconveniences to the customer. Normally, the utility shall determine the
				location and type of metering equipment to be installed.
(2) The utility should have available for
				distribution to customers, architects, contractors and electricians copies of
				rules, specifications and requirements that may be in force relative to meter
				installations. Installations should conform to such specifications and to
				applicable codes and safety requirements.
(3) Whether installed indoors or outdoors,
				meters should not be located where they will be subject to vibration or
				mechanical damage and should be mounted without tilt.
(4) Meters and associated equipment used on
				outdoor installations shall be designed specifically for such use or shall be
				suitably housed for outdoor service. Meters installed outdoors should not be
				located where they may be damaged, such as on buildings where unguarded meters
				will extend into alleys, walkways or driveways.
(5) Meters installed outdoors should not be
				more than 6 feet or less than 4 feet above final ground level (measured from
				the center of the meter cover) except in the case of meters on pedestals or
				padmounted transformers where they shall be placed as high as practicable and
				meters on underground services which may, when practicable, be placed as low as
				2.5 feet above final ground level (measured from the center of the meter
				cover). On individual installations indoors, the meter should be not more than
				6 feet or less than 4 feet above floor level (measured from the center of the
				meter cover). On group installations of meters indoors, no meter should be more
				than 6 feet or less than 2 feet above floor level (measured from the center of
				the meter cover). When a number of meters are placed on the same meter panel
				the distance between centers should be not less than 8.5 inches vertically or
				7.5 inches horizontally. For meters installed both indoors and outdoors there
				should be a minimum of 3 feet of unobstructed space in front of the meter from
				the surface on which it is mounted.
(6) When there is more than one meter at a
				location, each shall be so tagged or marked as to indicate the circuit metered.
				Where similar types of meters record different quantities (for example,
				kilowatt-hours and reactive power) the meters shall be tagged to indicate what
				they are recording.
(7) Test
				facilities shall be placed in enclosures of sufficient size and of such
				construction as to make it possible for meter testers to perform the tests
				required by these rules with safety.
