Ground lights should be tested and kept in working condition. Which statement is true?

• A. True
• B. False
• C. They should be replaced only if damaged
• D. They are optional in most installations

Answer: (A)

Ground lighting is a safety feature that confirms the electrical system has a proper grounding path. Having a visible, functioning ground indicator helps workers know that metal parts are bonded to earth before touching or servicing equipment, reducing the risk of shock or unintended contact with a live conductor. Because grounding is a critical safeguard, these lights must be kept in working condition and tested regularly as part of preventive maintenance. A test verifies that the indicator responds when the equipment is connected to earth and that the lamp, circuit wiring, and any fuses or switches in the path are functioning. If the light is out, it could mean the lamp is burned out, the wiring is open, or the grounding path itself is compromised, any of which should be addressed promptly. Since the goal is to maintain a reliable indication of proper grounding, these lights are not optional components and should not be replaced only if visibly damaged; they deserve routine testing and maintenance to ensure safety during operation and service.
