6.What is a terminal block

When you have a set of electrical wires to connect, a terminal block provides a safe, convenient way to keep them organized. They are rugged, easy to use and designed to keep wires of varying gauges securely connected.

Function

A terminal block is a set of two or more similar screw-down connection points. You can connect wires

at these points. A terminal strip combines many similar blocks in a single device. In a strip, the blocks are insulated from one another.

Materials

A terminal block's main functions are to connect and to insulate. The main block body is made of a tough material, such as plastic or ceramic, that electrically isolates adjacent blocks. The conducting parts are made of copper and corrosion-resistant metals compatible with copper.

Use

A terminal block must first be mounted in a safe, stable location away from moisture. To use it, strip

about ½ inch of insulation from the two wires you want to connect. You then insert the bare wires into the block's metal connectors and screw them down until they're securely fastened.

Special Functions

While most terminal blocks simply create an electrical connection, some have built-in fuse holders, indicator lamps or other features that add functionality for more sophisticated applications.

Variety

You can find dozens of types of terminal blocks, some generic, some specialized. Designers have developed terminal blocks for household, industrial, electronic and many other uses.

Labeling

You can use a terminal block to organize wires having different functions. Many terminal blocks have a labeling scheme that lets you identify how the wires are organized.
