What is a Terminal Block?
A terminal block, also called terminal board or terminal strip, is a modular, insulated block which connects one or more circuits to another. The connections are usually made by a screw or clamp lowering onto a bare wire to complete the connection. They offer a convenient way of connecting individual electrical wires because they don't require a splice or physically joining the ends.
What does a Terminal Block do?
A terminal block creates an electrical connection when the wires are clamped down to the metal part of the block by a screw. They usually contain two long aluminum or copper strips that are designed to connect different components. These strips create a bus bar for power distribution that is sent to the connected components.
Where should I use a Terminal Block?
Terminal blocks are commonly used in electricity wiring, to connect switches, and for connecting major appliances to plugs at home.
