Connectors
Box lug connectors are designed for use with a single or
multiple, solid or class B or C stranded conductor. For UL
approved use of more than one conductor per connector
opening, contact Littelfuse Technical Service. Manufacturers
of cable terminations 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.
Description
POWR-BLOKS
TM
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.
