Ground fault circuit interrupters (GFCIs) are essential safety devices designed to protect people from electric shock, particularly in environments where electricity may come into contact with water. They are required whenever there is a risk of a ground fault, which can occur in various settings that involve electrical power tools and cords.

Utilizing electrical power tools and cords inherently carries the risk of accidental contact with water or wet surfaces, making it crucial to have GFCIs in these situations. This requirement helps to ensure that if a fault occurs, the GFCI will promptly cut off the electrical current, reducing the chance of electric shock.

While GFCIs are indeed necessary in wet areas, that requirement extends beyond just connections in such locations. They are required for any usage scenario involving electrical power tools and cords, reinforcing the importance of maintaining safety standards in all operational environments, especially in construction or outdoor settings where conditions can vary.
