What is the purpose of pulling fuses during testing?

• A. To cut off power supply
• B. To test the circuit's integrity
• C. To confirm timer functionality
• D. To reset the timers

Answer: (C)

The purpose of pulling fuses during testing is primarily to cut off the power supply. By disconnecting the fuses, you can safely work on or test the electrical circuit without the risk of electrical shock or damaging equipment. This action ensures that no current flows through the circuit while you are inspecting or performing tests. Cutting off the power not only protects the technician but also allows for a clearer understanding of any issues present in the circuit when it is de-energized. It does not directly pertain to confirming timer functionality or resetting timers, as those tasks occur under different conditions or require different testing methods. Thus, understanding the significance of pulling fuses primarily revolves around safety and ensuring accurate testing conditions within electrical systems.
