MOST RECENT CHANGES

DATE MFG. CATALOG # STATUS REASON
12/2017 Talon (formerly Landis & Gyr)  9810-9802 Removed 600 Amps (CI 480) (Bolt-in metering)
 Note 7   Removed 480 V Meter Bases

NOTES:

  1. All meter bases listed in this table are "ringless" style. Horn bypasses are required in all ringless bases. Class 320 bases must contain a lever bypass rated 100% continuous duty.
  2. Meter bases used for 208/120 volt, 3 wire services must have a 5th terminal installed in the 9 o'clock position. The catalog number for the 5th terminal is listed in the "5th Terminal Accessory" column in the table and must be specified when purchasing the meter base.
  3. The manufacturer's catalog number must be stamped on the outside of the meter base so that it will be visible after the base is installed. The number must not be stamped on the cover.
  4. When aluminum conductors are used, the electrical contractor must apply the corrosion inhibiting compound recommended by and in the manner prescribed by the cable manufacturer.
  5. Prefix "H" on Talon (formerly Landis & Gyr) bases indicates bases that are sold through national retailers.
  6. 320 Amp Meter Bases:
  • All 320 amp meter bases contain stud terminals.
  • Only UL approved lay-in or box style connectors suitable for use with copper or aluminum conductors can be installed for wire termination on the studs.
  • Compression connectors are not permitted.
