POWR-BLOKSDistribution/Splicer Blocks Covers
connectors designed with single, solid class stranded conductor. more than conductor connector opening extra-flexible, fine stranded conductors, such welding cable, voids Listing, cause overheating. Manufacturers cable terminations furnish crimp-on sleeves fine stranded conductors which permit these conductors used with lugs.
Ampere Ratings
ampere rating pole power distribution blocks based line ampacity 75°C insulated conductors Table 310.16. 60°C insulated conductors used, load must exceed ampacity 60°C conductors. conductors rated excess 75°C permitted (for example 90°C), however, load must exceed ampacity 75°C conductors.
Ordering Information
POWR-BLOKS power distribution blocks offer safe, convenient splicing cables, providing fixed junction tap-off point splitting primary power into secondary circuits. LX2xxx-DIN series offers integral DIN-Rail mount optional hinged safety cover.
Distribution Block Example Part
Splicer Block Example Part
Applications
Typical applications include heating, conditioning refrigeration systems, elevator systems, material handling equipment, control panels, motor controls, switchgear, anywhere power needs distributed more than load.
Note: Aluminum blocks copper aluminum wire; copper blocks only copper wire.
