Harsh Environment High-Current Distribution Bars
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.

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.
Extendable blocks attach to each other to create custom-sized distribution blocks.
Blocks with a detachable cover prevent accidental contact with live circuits.
