🔍 Key Concepts

• Ground-detecting system indications and what they tell you • The safest way to isolate a fault without endangering equipment or personnel • Difference between system-wide tests and circuit-by-circuit checks

💭 Think About

• Ask yourself: When you have multiple grounds that appear as one, do you start by opening up the system in a controlled way, or by testing each piece of equipment individually? • Which option reduces risk to the switchboard and equipment while helping you narrow down which branch of the system has the problem? • Think about normal troubleshooting sequence: do you first try to change power sources, or do you work on the distribution side of the problem?

✅ Before You Answer

• Which choice focuses on systematic isolation of circuits rather than immediately changing power sources or using test instruments? • Which action can be done while the system is energized but in a controlled way, and helps you see when the ground indication clears? • Avoid an option that could create additional hazards or damage if the ground is still present (for example, parallel operation or unnecessary switching of generators) before you know where the fault is.
