If an extension cord does not have a ground terminal, what should you do?

1. Use it as is

2. Wrap the terminals with tape

3. Replace it

4. Only use it for low power tools

The correct answer is: Replace it

Using an extension cord without a ground terminal poses a significant safety risk, particularly when powering tools and equipment that require grounding for safe operation. Grounding helps to prevent electric shock by providing an alternative path for electrical current in case of a fault. An extension cord lacking this feature may not adequately protect users from potential electrical hazards. Replacing the extension cord is the best approach, as it eliminates the risk associated with using an ungrounded device. By opting for a grounded extension cord, you ensure that all electrical equipment can operate safely and you minimize the chance of electrical accidents. This is especially crucial in environments where water or damp conditions may occur, as ungrounded tools can lead to increased risks of electrocution. In contrast, using an ungrounded extension cord as is, wrapping the terminals with tape, or restricting its usage to low power tools does not ensure safety and may leave users exposed to serious electrical hazards. It's important to prioritize safe practices when dealing with electrical equipment.
