Electronics are used on boats for multiple purposes. Lights require electricity, as do speakers, receivers, navigation systems and many other pieces of equipment. Where there are electronics, there should be electrical terminals. A marine terminal block is a modular block with an insulated frame which secures two or more conductors.
