Which type of GFCI is typically found on construction sites?

The type of GFCI that is typically found on construction sites is the extension cord with built-in protection. These specialized extension cords are designed to provide ground fault circuit interruption directly at the point of use, ensuring that workers are protected from electrical shock hazards that may occur in damp or outdoor conditions commonly encountered on construction sites.

By integrating GFCI protection into the extension cords, they serve as a portable solution, allowing workers to easily connect tools and equipment while maintaining safety standards. This is particularly important in environments where water or other conductive materials are present, as traditional receptacle-based GFCIs may not provide the same level of mobility and convenience.

GFCI breakers, receptacles, and built-in panel GFCIs have their specific uses and advantages, primarily in permanent installations or situations where more extensive electrical systems are set up. However, for the dynamic and often temporary nature of construction sites, extension cords with built-in GFCI protection provide the ideal combination of safety, convenience, and adaptability.
