UL Recognized power distribution blocks
Catalog number example:
16220-3 is a 3-pole 16220
Where:
The prefix 16220 defines the blocks lineside
characteristics (i.e., one conductor port per
pole that accepts 2/0 - #14 Cu, or 2/0 - #8 Al
conductors) and the loadside characteristics
(i.e., four conductor ports per pole that each
accepts #4 - #14 Cu or #4 - #8 Al conductors).
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

* 75C wire (higher temperature rated wire acceptable with appropriate derating). Using a ferrule on a stranded conductor requires a correctly sized UL Listed ferrule
(customer supplied) applied according to the manufacturers specifications. Ferrule ratings apply to copper wire only.
** Not covered by CSA certification.
See Short-Circuit Current Ratings table for the tested upstream overcurrent protective devices necessary for achieving these SCCRs.
Torque rating for dual wire and ferrule application is 30.5 Nm (270 Lb-in).
Configuration includes hex screws.
