Question

Technician A says to check the circuits fuse if the actuator is not receiving power. Technician B says if a 15 amp fuse continues to blow to replace it with a 20 amp fuse for added protection. Who is correct?

A. Technician A
B. Technician B
C. Both A and B
D. Neither A or B

Answer 1

Technician A is correct in advising to check the circuit's fuse if the actuator is not receiving power. Technician B is incorrect in suggesting to replace a 15 amp fuse with a 20 amp fuse for added protection.

Step-by-step explanation:

A fuse is a device that protects a circuit from currents that are too high. It consists of a piece of wire between two contacts, and when a current passes through the wire that is greater than the rated current, the wire melts, breaking the connection. Therefore, Technician A is correct in advising to check the circuit's fuse if the actuator is not receiving power. Technician B, on the other hand, is incorrect. Fuses are designed to protect circuits from overheating and potential damage by breaking the connection when the current exceeds the rated limit. Replacing a 15 amp fuse with a 20 amp fuse can lead to excessive current flowing through the circuit, posing a safety risk. It is important to always use the correct fuse rating to prevent damage to the circuit and potential hazards.
