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.
