If a power tool has a 3-pronged plug but only 2-pronged outlets are available, what action should a technician take?

Use an adapter for the plug
Locate a 3-pronged outlet
Modify the tool to fit the outlet
Consult the tool manufacturer for a solution

The correct answer is: Locate a 3-pronged outlet

Using a 3-pronged outlet is the safest and most appropriate action when a power tool is equipped with a 3-pronged plug. This type of plug typically includes a grounding prong that provides additional safety against electrical faults. By plugging into an outlet that supports this configuration, the technician ensures that the tool is properly grounded, minimizing the risk of electric shock or fire. If a technician were to use an adapter for a 2-pronged outlet, it would defeat the safety feature of the grounding prong, thus increasing the risk of electrical hazards. Modifying the tool to fit a 2-pronged outlet would also compromise its safety and could void any warranties or violate safety standards. Consulting the manufacturer for a solution might be a good option, but it would not address the immediate need for using the tool safely and effectively. Therefore, locating a compatible 3-pronged outlet remains the best course of action.
