What safety feature must electric corded tools and equipment use?

Electric corded tools and equipment must use GFCI (Ground Fault Circuit Interrupter) or other acceptable means of grounding as a crucial safety feature. GFCIs are designed to protect users from electric shock by monitoring the electrical current flowing through the circuit and shutting off the power if an imbalance is detected, which typically indicates a potential leakage current or ground fault. This is particularly important in environments where tools might be used near water or where the potential for encountering moisture is higher, making it easier for electrical currents to escape and cause harm.

While overload protection, circuit breakers, and surge protectors are also useful for electrical safety, they serve different functions. Overload protection prevents the risk of overheating and damage to tools but does not specifically address the risk of electric shock. Circuit breakers can protect against overloads and short circuits, but they do not provide immediate protection in the event of ground faults, which is a critical aspect of user safety. Surge protectors guard against voltage spikes but do not mitigate the risk of electric shock. Therefore, the specific requirement for grounding through GFCI is essential in ensuring the safety of those using electric corded tools and equipment.
