Blocks and Holders Blocks and Holders POWR-BLOKS Distribution/Splicer Blocks and Covers Connectors Box lug connectors are designed for use with a single, solid or class B or C stranded conductor. Use of more than one conductor 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 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 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.
