Another very common function for terminal blocks is grounding. Grounding refers to connecting an object to the Earth in the most effective way with the help of conducting wires. Grounding terminal blocks facilitate safe and efficient termination of a device and panel grounding wires to the DIN rail using a conducting metal clamping foot. This specific type of terminal block is used to ground components or systems. Ground blocks are typically interchangeable with standard terminal block sizes, so they can be used as needed. Grounding terminal blocks are recognized with an industry standard and easily identifiable green-yellow color.
