When testing a 110 VAC outlet with a pocket VOM, to what range should you set it?

When testing a 110 VAC outlet, setting the pocket volt-ohm meter (VOM) to a range of 250 VAC is appropriate because it allows for accurate readings while providing a safe margin above the expected voltage. While the outlet nominally provides 110 VAC, it can vary due to factors like load and supply conditions, often reaching up to 120 VAC in practice. Selecting a 250 VAC range ensures that the meter can handle the voltage without being overextended or risking damage to the device.

Using a setting lower than 250 VAC could limit the meter’s ability to function properly or accurately read voltage if it fluctuates above the selected range. With a higher range, you maintain both accuracy and safety during the measurement process, making it suitable for testing standard household outlets.
