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 slee ves 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 75C insulated conductors per
NEC Table 310.16. If 60C insulated conductors are used,
load must not exceed the ampacity of 60C conductors.
Use of conductors rated in excess of 75C is permitted (for
example 90C), however, load must not exceed the ampacity
of 75C conductors.
