POWR-GARD Blocks and Holders Datasheet POWR-BLOKS Distribution Blocks Splicer Blocks Covers 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. Description Specifications TM POWR-BLOKS power distribution blocks offer a safe, Voltage Rating 600 V convenient way of splicing cables, providing a fixed junction Current Rating Based on NEC Table 310.16, using 75C copper wire tap-off point or splitting primary power into secondary SCCR Consult Factory circuits. Lx2xxx-DIN series offers integral DIN-Rail mount Material Phenolic rated at 150C and Thermoplastic rated at 125C (LD1400 and LS1300 series only) and an optional hinged safety cover.
