🔍 Key Concepts

• Ground-detection lights on a main switchboard and what they actually tell you • Difference between locating a ground vs. confirming insulation resistance • Safe, systematic isolation of circuits using breakers or switches

💭 Think About

• Ask yourself which method lets you safely and logically narrow down which specific branch circuit has the ground, without immediately using test equipment on energized gear. • Consider which option you could perform step-by-step on a live system, watching the ground indicator as you go, to see when the indication disappears. • Think about shipboard practice: when a ground light shows, what is the first, most practical troubleshooting action most engineers take at the distribution panel?

✅ Before You Answer

• Does the choice involve a systematic way to isolate one circuit at a time and observe a change in the ground indication? • Is the method safe to perform on an energized distribution system, following normal operating practice? • Does the method focus on finding which circuit is grounded, not just measuring overall insulation or visually hunting damage?
