    Blocks with a screw-clamp terminal input wire connection have a current rating based on NEC table 310-16 using 75° C copper wire.
    Extendable—Extendable blocks attach to each other to create custom-sized distribution blocks.
    Jumper Cable Terminal—Blocks with a jumper cable terminal connect to other blocks to increase the number of outputs.
    Detachable Cover—Blocks with a detachable cover prevent accidental contact with live circuits.
    Quick-Disconnect Load Connection—Blocks with a quick-disconnect load connection let you attach an auxiliary device, such as a horn or light.
    Terminal Block End Stops—End stops (sold separately) mount at the end of a group of blocks to prevent movement.
