  • Please make sure temporaries are in good working condition and neutrals are properly marked. The name of the Electrical Contractor must also be on the temporary service.
  • The breaker panel cover must be installed before MMU can install a meter or energize the service per OSHA regulations.
  • Service lines must be installed all the way to the transformer or pedestal (hand dig near transformer or pedestal) at a minimum depth of 24".
  • Leave at least 4 feet of wire above the transformer or pedestal for hookup.

  • As a part of the wiring for any new home or apartment or any remodeling or rewiring project, a 3 wire low voltage conductor (18 AWG) must be run for the remote reader for water meters. Please install the conductor from the area of the water meter to the area of the electric meter.


  • All NEW or remodeled and/or rewired Residential units must be individually metered, with the exception of multi-unit facilities providing care to elderly or disabled persons.

In addition to apartments, duplexes, triplexes etc., this includes homes with more than one separate kitchen and bath facility.
  • Buildings used for Commercial business may be individually metered for each business or may be master metered, BUT MAY NOT BE A COMBINATION OF THESE TYPES OF METERING. If individually metered, the rate class of each business in the building will be determined by their individual electric consumption. For master metered buildings with demands less than 75 KW, the Commercial Rate will apply and the fixed charge will be multiplied by the number of the businesses served and added to the energy charge to obtain the total billing. For master metered buildings with demands of 75 KW or greater, the Demand Metered Rate will apply.
