Terminal Blocks & Busbars

Reliable boat wiring is made at its connection points. This collection covers the hardware that keeps 12V systems tidy and serviceable: Blue Sea marine terminal blocks in 20 and 30 amp ratings, busbars for distributing power and gathering negatives, terminal fuses, and crimp connectors - ring, bullet, push-on and fully insulated terminals - plus crocodile clips for test leads.

Terminal blocks let circuits be joined, labelled and altered without soldering irons and heroics; busbars replace the tangle of doubled-up terminals at the battery switch with one clean distribution point. Use marine-grade tinned terminals, crimp with the correct tool, and cover connections with heat-shrink where damp can reach - the ten extra minutes at installation saves the mystery faults later.
