🔍 Key Concepts

• Grounding in electrical systems and what it protects people from • What happens if a metal-cased tool develops an internal short to its frame • Difference between protecting the person versus protecting the motor or equipment

💭 Think About

• Ask yourself: If the tool’s hot wire touches the metal case, who or what is in danger without a ground? • Which answer choice focuses on protecting the user, not just the tool’s motor or components? • Is the main purpose of a ground connection to stop damage to the tool, or to provide a safe path for fault current away from your body?

✅ Before You Answer

• Identify which option directly addresses user safety from current passing through the body. • Eliminate any choices that only mention damage to the motor or tool, not injury to the operator. • Think about what a ground wire does: it gives fault current a low‑resistance path so it doesn’t go through you.
