Testing Fuses Safely with an Ohmmeter

What is the first step when testing fuses with an ohmmeter?

A. Turn power to the circuit off and lock out and tag the disconnect

B. True

Answer:

The first step when testing fuses with an ohmmeter is to turn off the power and lock out and tag the disconnect to ensure safety and accurate readings.

When testing fuses with an ohmmeter, the first step is crucial to ensure safety and accurate results. By turning off the power to the circuit and locking out and tagging the disconnect, you prevent any potential hazards that could arise from live circuits.

An ohmmeter measures resistance, and testing a fuse accurately requires the circuit to be de-energized. If the power is not turned off, the ohmmeter may give incorrect readings, posing risks of electric shock or equipment damage.

Therefore, always prioritize safety by following the correct procedures when testing fuses with an ohmmeter. This initial step sets the foundation for a successful and secure testing process.
