Rule 14 - Meters -- Secondary Service -- Self-contained Installations

  1. Self-Contained Metering:

    Customer installs and maintains an approved meter base specified by PPL EU for self contained meters.

    PPL EU specifies self-contained meters as follows:

    Self-Contained Meter Table

    Meter Class

    Phase

    Voltage

    Service Size
    200 1 120/208 (Network) Up To And Including 200A
    200 1 120/240 Up To And Including 200A
    200 1 240/480 Up To And Including 200A
    200* 3 208Y/120, 4 wire Up To And Including 200A
    200* 3 240Δ, 4 wire Up To And Including 200A
    320 1 120/208 (Network) 400A
    320 1 120/240 400A
    320** 3 208Y/120, 4 wire 400A
    320** 3 240Δ, 4 wire 400A

    * No individual phase current shall exceed 200A

    ** No individual phase current shall exceed 320A

  2. Meter Bases:

    The table of Approved Meter Service Devices list the PPL EU approved meter bases and the minimum and maximum conductor sizes for the approved meter bases. Install one conductor per terminal.

    Installation of multiple terminal lugs is permitted in Class 320 meter bases.

    PPL EU specifies meter bases capable of accepting 350, 500 or 750 kcmil conductor if loads or service distance deems it necessary.

    Sketch #25 and Sketch #25A show typical meter base connections.

  3. Location of Meter Base and Service Disconnect:

    The meter base is installed in the line side of all service protective equipment except where a main service disconnect is required by the National Electrical Code.

  4. By-Pass Facilities:

    Manual type by-pass facilities are required on all ringless meter bases. By-passes are not permitted on ring type meter bases.
