When conducting an AC voltage test, where should the test probes be placed?

The correct placement of the test probes for an AC voltage test is into the two slotted openings of a receptacle. This method allows for the most accurate measurement of the voltage present between the live (hot) and neutral wires.

By inserting the probes into the two slotted openings, one probe contacts the hot wire and the other contacts the neutral wire, creating a complete circuit that enables the meter to register the voltage. This is essential for confirming that the outlet is functioning correctly and providing the appropriate voltage for electrical devices.

When probes are placed in other positions, such as on the outer casing of the receptacle, they do not measure the voltage across the circuit properly, and therefore do not provide a valid reading of the outlet’s electrical status. Similarly, inserting the probes into the ground and neutral connections or into a single slot would not result in a proper or meaningful measurement of AC voltage, as these methods do not create the necessary circuit path for voltage testing. Thus, using both slotted openings of the receptacle is the correct approach for assessing AC voltage.
