Q

(1.1.10.2.2-2) When replacing fuses, what practice should be observed?

🔍 Key Concepts

• Overcurrent protection devices (fuses vs. circuit breakers) and what their main safety purpose is • Safe maintenance practices when working on electrical fuse holders and panels • Why changing the fuse rating can be dangerous to the circuit and wiring

💭 Think About

• Ask yourself: which option focuses on the actual condition of the fuse holder and the electrical contact, rather than on personal protective equipment? • Consider what could happen to the wiring and equipment if you routinely install fuses with ratings higher than specified. • Think about what the main problem is when a fuse overheats or arcs at the contact points—does PPE fix that, or does something else address the root cause?

✅ Before You Answer

• Check which choice directly ensures good electrical contact and proper seating of the fuse in its holder. • Verify which option would change the designed protection level of the circuit (this is usually unsafe). • Confirm which options are more about general shock protection vs. the specific recommended practice when replacing a fuse itself.
