Description:
How do we connect two wires? By stripping the insulation at the ends and twisting them together? Yes, it works. But, is it safe? We can apply insulation tape over the joint or use a wire connector. But what if there are a number wires that need to be joint/connected near each other? Or, what if multiple outgoing wires are to be connected to a single incoming wire? Then this method will neither be safe nor be convenient anymore. Here we use terminal blocks.
A terminal block (also called as connection terminal or terminal connector) is a modular block with an insulated frame that secures two or more wires together. It consists of a clamping component and a conducting strip.
Compared to other types of connectors, terminal blocks are low in cost. And it can be re-used in the field, allowing for the replacement of wires or equipment, generally with standard hand tools. It usually avoid the requirement for a specialized mating connector to be applied to the ends of wires.
Applications:
The terminal blocks are used in almost all electric appliances that need 240-volt power supply.

Terminal blocks selection guide:
The difference between blocks can lead to problems if an incorrect type is used or if it is not connected properly. Follow the advice below to choose the right one:
• Look at the electrical equipment you are working on to see what type of connection it requires; normally you will have either a screw-in or plug-in connection. Screw-in wires are placed inside the terminal block and screwed into position, and they are most common for equipment that does not require high voltage protection. A variation on the screw-in connection is one held in place by a spring mechanism. This connector can reduce the time spent on the job because you simply clip it into place instead of removing and replacing the screw.
A plug-in connection has a male terminal at the end of the wire. This terminal is connected to the female port on the terminal block and forms a secure connection. Plug-in blocks are commonly used in the fuse boxes of automobiles.
• Once you know the type of connection that is required, you need to find a terminal block that fits the rest of your requirements. Consider what space you have for the connection and how many wires need to be connected. Terminal blocks are supplied in a variety of shapes and sizes, so you should be able to find one that suits your needs.
• Choose the correct rating. 3A, 5A, 15A, or 30A terminal blocks are widely available, and you'll want to buy the one that meets the highest current level that it will conduct in order to allow the most powerful piece of equipment to function.
