If you bring in an extension cord into the crawlspace, make sure there is ___________. Many cords have ______________ integrated in the cord.

The correct answer is that if you bring an extension cord into the crawlspace, it is essential to ensure that there is GFCI protection. GFCI, which stands for Ground Fault Circuit Interrupter, is critical in areas where electrical equipment may come into contact with moisture, such as a crawlspace. The integrated protection helps prevent electrical shock by monitoring the current flow and shutting off the circuit if it detects an imbalance, indicating a potential fault.

Many extension cords are designed with GFCI protection integrated within the cord itself. This feature enhances safety by providing an additional layer of protection directly at the point of use, making it suitable for the potentially damp environment of a crawlspace.

Ensuring GFCI protection when using electrical equipment in such environments is crucial for safety, as moisture can significantly increase the risk of electric shock. In contrast, options related to waterproofing, insulation, high and low voltage, or surge protection do not specifically address the electrical hazard posed by moisture, which is the primary concern when working in a crawlspace.
