Distribution/Splicer Blocks and Covers
Description
POWR- BLOKSTM power distribution blocks offer a safe,
convenient way of splicing cables, providing a fixed junction
tap- off point or splitting primary power into secondary
circuits. Lx2xxx-DIN series offers integral DIN-Rail mount
and an optional hinged safety cover.
Optional power distribution block covers provide protection
against accidental shorting between poles caused by
loose wires, tools, or other conductive material. They also
protect personnel from accidentally contacting energized
connectors. To order protective covers, match the number
of poles for the block to the cover.

Applications
Typical applications include heating, air conditioning and
refrigeration systems, el e va tor systems, material handling
equipment, control panels, motor controls, switchgear, and
anywhere power needs to be distributed to more than one load.
Connectors
Box lug connectors are designed for use with a single, solid
or class B or C stranded conductor. Use of more than one
con ductor 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
ter minations can furnish crimp-on sleeves for fine stranded
conductors which permit these conductors to be used
with box lugs.
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.
