🔍 Key Concepts

• Safe work practices on high voltage electrical systems • Difference between live-line testers and off-line testers • Correct sequence of testing and grounding a de-energized circuit

💭 Think About

• Think about what could happen if you apply a ground to a circuit that is actually still energized. • Which type of tester is designed to confirm a circuit is de-energized before anyone connects grounds or makes contact? • Why is the order of "test" and "ground" so critical for personal safety on high-voltage systems?

✅ Before You Answer

• Confirm whether a circuit must be proven de-energized (dead) before grounding is applied. • Identify which instrument is appropriate for verifying absence of voltage, not for live work. • Check the logical safety sequence: disconnect/isolate → verify de-energized → apply grounds.
