Panels and equipment chassis can be grounded with ground screws or __________.

Grounding panels and equipment chassis is a critical aspect of electrical system installations, ensuring safety and protection against electrical faults. Ground screws are commonly used for this purpose, and terminal blocks serve as an effective alternative for grounding.

Terminal blocks are designed to facilitate the easy connection of multiple wires and can be utilized to create a reliable grounding point. They allow for the secure connection of grounding wires to a chassis or panel, ensuring that electrical current has a safe path to the ground in the event of a fault. This capability is vital for maintaining the integrity of the electrical system and protecting both the equipment and individuals from potential electric shocks.

The other options do not fulfill the requirements for grounding in the same way. For example, cable ties are used for bundling wires and securing them but do not provide electrical connectivity. Wire nuts serve to connect and insulate multiple wires but are not specifically designed for grounding purposes. Ground rods are used in grounding systems as a physical connection to the earth but do not connect directly to panels or equipment chassis in the same manner as terminal blocks.
