Using ground fault circuit interrupters (GFCIs) or an assured grounding conductor program is a critical safety measure for electrical power tools on construction sites because these devices provide essential protection against electrical hazards. GFCIs are designed to prevent electrical shock by monitoring the current flowing through a circuit and cutting off the power if an imbalance is detected, which can occur if electricity takes an unintended path, such as through a person. This is particularly important in construction environments where tools may come into contact with water or be used in damp locations, increasing the risk of electrical shock.

Implementing an assured grounding conductor program ensures that tools are properly grounded, which is an essential safety feature designed to protect users from electrical faults. Both GFCIs and grounding practices significantly enhance safety and reduce the likelihood of accidents on site, making them a fundamental requirement in the electrical safety protocols for power tools used in construction.
