Terminal Blocks

Terminal blocks join two or more conductors inside an insulated body clamped to a rail, giving every wire a numbered, testable landing point instead of a splice buried in a loom. Wiring crews fit them when a circuit has to be terminated where it can be tested and disconnected, when a scorched block shows a connection has been running loose, or when a rebuild needs blocks matched to the cable sizes already pulled.

 

As an authorized electrical distributor for multiple manufacturers, we stock terminal blocks from ABB, Appleton and more across competing lines, in a range of cable sizes, barrier styles and amperage ratings, so you can match the conductor size and rail the panel uses, compare barrier styles and ratings across brands, and terminate a circuit somewhere it can be tested.
