ORDERING INFORMATION
Distribution Block
Example Part No.
Splicer Block
Example Part No.
POWR-BLOKS™ power distribution and splicer blocks offer a
safe, convenient way of splicing cables, providing a fixed
junction tap-off point, or splitting primary power into secondary
circuits. Blocks have one or two primary inputs, with up to
twelve secondary outputs per pole. The number of poles
available ranges from one to three.
APPLICATIONS
Typical applications include heating, air conditioning and
refrigeration systems, elevator systems, material handling
equipment, control panels, motor controls, switchgear, and
anywhere power needs to be distributed to more than one load.
AMPERE RATINGS
The ampere rating per pole for power distribution blocks is
based on the line ampacity of 75° C insulated conductors per
NEC Table 310-16. If 60° C insulated conductors are used,
load must not exceed the ampacity of 60° C conductors. Use
of conductors rated in excess of 75° C is permitted (for
example 90° C), however, load must not exceed the
ampacity of 75° C conductors.
BLOCKS
AND
CONNECTORS
Box lug connectors are designed for use with a single, solid or
class B or C stranded conductor. Use of more than one conductor
per connector opening or use of extra-flexible, fine stranded
conductors, such as welding cable, voids the UL Listing, and may
cause overheating. Manufacturers of cable terminations can
furnish crimp-on sleeves for fine stranded conductors which permit
these conductors to be used with box lugs.

Power Distribution Block Covers provide protection against
accidental shorting between poles caused by loose wires,
tools or other conductive material. They also protect person-
nel from accidentally contacting energized connectors.
