Technical FAQs 4

Can a DC supply be grounded?

In these systems, there are two connection configurations: floating and grounded. Although grounding a DC supply can often be a preferred method, it can introduce other problems including ground loop interference among sensors and a possible problematic current leakage to ground.

Should a cabinet be grounded if it is not painted?

If the cabinet is not painted, zinc coating treatment inside ensures that all mechanical joints conduct properly. If the cabinet is painted, all components and installation plates should be grounded via a cable to the grounding busbar. Body grounding does not replace a protective earth connection.

What happens if a voltage supply is grounded?

If this current comes from the output into a grounded DC system, it will return through the ground wire, causing a trip of a ground-fault breaker. It is nearly impossible in any discussion of grounding voltage supplies to provide a definitive recommendation on whether it is best practice or not.

Does an ungrounded DC derived system need a grounding electrode conductor?

An ungrounded DC separately derived system fed from a stand-alone power source must have a grounding electrode conductor connected to an electrode complying with Part III of Article 250, “Grounding electrode system and grounding electrode conductor.”
