Frequently Asked Questions (FAQs)

1. Can you use a terminal block for grounding?

Grounding / Earthing Terminal Blocks are used for grounding and earthing wires to protect people and machinery from intrusion such as electrical or magnetic fields.

2. Can DIN rail be used for grounding?

Grounding terminal blocks are used to mechanically and electrically connect wires to the DIN rail by means of a conducting clamping foot. In this way, the DIN rail can function as a ground bus bar. Grounding terminal blocks are molded in green and yellow per international standards.

3. How do you ground DIN rail?

Secure the DIN rail to the backplate with the screws and washers included with the DIN rail. If a ground wire is included, slide the eyelet on one end of the ground wire over one of the mounting screws prior to securing the DIN rail. The other end of the ground wire is secured to the enclosure ground terminal.

4. What is DIN rail terminal blocks?

DIN rail and channel terminal blocks are rack or box mount connection points for securing two or more wires to a circuit or power bus. Certain types may include a single or dual disconnect fuse or switch feature, feed-through capability, grounding, built-in indicators and resistors, isolation and circuit protection.
