Distribution Blocks
With the help of distribution blocks, you can take a high-current wire from your power source and connect it to one or more electrical devices.
Blocks with a screw-clamp terminal input wire connection have a current rating based on NEC table 310-16 using 75° C copper wire.
Choose blocks with a bus-bar input wire connection to distribute power from flat conductors without the need for an adapter.
Extendable blocks attach to each other to create custom-sized distribution blocks.
Blocks with a jumper cable terminal connect to other blocks to increase the number of outputs.
Blocks with a quick-disconnect load connection let you attach an auxiliary device, such as a horn or light.
Blocks with a detachable cover prevent accidental contact with live circuits.
End stops (sold separately) mount at the end of a group of blocks to prevent movement.

Protect connections against corrosion. These bars are tin-plated copper and have stainless steel terminals. Also known as bus bars, they serve as connection points between wires with ring or spade terminals. The underside is sealed, so the bars can be safely mounted to conductive surfaces.
Covers protect the top of the bar and prevent accidental contact with live circuits.
