Effective January 2017 Technical Data 10535 Supersedes November 2017 Stud blocks Catalog number example: 16280-3 is a 3-pole 16280 Where: The prefix 16280 defines the blocks lineside characteristics (i.e., one conductor port per pole that accepts 2/0 - 14 Cu/Al conductors) and the loadside characteristics (i.e., 1/4-20 x 3/4 stud). The suffix 3 in this example defines this as a three-pole block. See the catalog number tables for details on the available lineside/loadside characteristics. How to order: From the catalog number tables, select the catalog number that defines the desired lineside/loadside port and conductor characteristics. Add to the catalog number the suffix that defines the desired pole configuration. Note, you must select from the available number of poles for each catalog number. These appear in the second column of the catalog number tables.
