When selecting extension cords for power tools, power requirements, wire gauge, and length of run are essential considerations.

Understanding the power requirements is crucial because extension cords must be able to handle the voltage and current needs of the tools being used. If the cord is not rated for the required power, it can lead to overheating and potential fire hazards.

The wire gauge is equally important; a lower gauge number indicates a thicker wire, which can safely carry more current. Using an extension cord with an appropriate wire gauge helps prevent voltage drop, ensuring the tools operate efficiently and safely.

Lastly, the length of the run affects the voltage drop as well. The longer the extension cord, the more resistance it has, which can reduce the voltage received by the tool. It's vital to select an extension cord that balances the necessary length with the tool's power requirements to ensure optimal performance.

Considering these factors collectively contributes to safe and effective use of power tools. The other options, while potentially relevant in broader contexts, do not directly impact the safe and efficient use of extension cords in relation to power tools.
