POWR-BLOKS™ Distribution/Splicer Blocks and Covers SPECIFICATIONS Voltage Rating: 600V Amperage: Based on NEC Table 310.16, using 75°C copper wire Material: Phenolic rated at 150°C and Thermoplastic rated at 125°C (LD1400 and LS1300 series only) Connector: Standard: Highly conductive aluminum, tin plated Copper: Highly conductive copper, tin plated Flammability Rating: 94V-0 Approvals: UL Recognized (File No. E171395) CSA Certified (File No. LR700111) NEW ORDERING INFORMATION Distribution Block Example Part No. POWR-BLOKS 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. Splicer Block Example Part No. APPLICATIONS Typical applications include heating, air conditioning and refrigeration systems, elevator systems, material handling equipment, control panels, motor controls, switchgear, and anywhere power needs to be distributed to more than one load. 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. 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.
