Terminal blocks/connector strips (also known as choc blocks) are ideal for connecting multiple wires independently for a more tidy and secure application. Connector strips can be cut to length while the terminal blocks are available in 4, 6 and 8 way variants. These connectors are commonly used in automotive applications but can also be used for marine wiring systems.
As a marine alternative we would recommend using bus bars or stud posts in conjunction which heat shrink sleeving and heat shrink terminals.
