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. The line (utility) terminals in all UG bases must be offset to the left or right of the socket to accommodate the installation of underground service wires.
6. Conduit Requirements:
   200 Amp Service
   The conduit KO directly under the line (utility) terminals must accept a 3 inch conduit.
   400 Amp (Cl 320) Service
   The conduit KO directly under the line (utility) terminals must accept a 4 inch conduit. The conduit KOs directly under the load terminals must accept two (2) 3 1/2 inch conduits.
7. Prefix "H" on Talon (formerly L&G) bases indicates bases that are sold through national retailers.
8. Talon (formerly L&G) Underground Base #UAS817-PPG and HUAS817-PPGP has line terminals mounted on right side of base. Durham UG Base #1004884 is available with line terminals mounted on right or left side of base (specify when ordering). All other bases have line terminals mounted on left side of base.
9. Class 320 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.
