The biggest advantage of terminal blocks is cost. They are cheaper compared to other types of connectors. It also saves time because the process of connecting wires is not as complicated as some others. Most well-equipped shops can 
easily connect wires using terminal blocks, just strip the wires.

By investing in multi-layer terminal blocks, you can reduce panel space by up to 50%. That's because a multi-level block contains a multi-level circuit with that single block. Terminal blocks improve safety by grounding, isolating, and 
protecting other components in the circuit. Terminal blocks provide a finger-safe connection to prevent electrical shock.

They can be installed with a screwdriver, ensuring quick connect/disconnect, which aids in maintenance and troubleshooting. When using electricity, electrical junction boxes are used to connect electrical switches and receptacles to the 
power source. Most terminal bodies are composed of a copper alloy that has the same coefficient of expansion as the wire intended for use.

Using the same expansion coefficient helps prevent loosening due to different expansion rates. It also reduces corrosion caused by electrolytic action between two dissimilar metals.
