How to use a multimeter to safely test the voltage of live wires?
To safely test the voltage of live wires using a multimeter, follow these steps: Set the multimeter to the voltage setting that is higher than the expected voltage of the live wires. Turn on the multimeter and touch the probes to the live wires, ensuring that they are securely connected. Read the voltage displayed on the multimeter screen. If the voltage is within the expected range, you can safely disconnect the probes. If the voltage is higher than expected, take caution and seek professional help. Remember to always wear insulated gloves and goggles when working with live wires to prevent electric shock.
