When using electric power tools, which type of cord should be used?

The use of a 3-wire cord with ground is essential for ensuring safety when operating electric power tools. This type of cord consists of three conductors: one for the live wire, one for the neutral wire, and a grounding wire. The grounding wire provides a safe path for electrical current to flow in case of a fault, preventing potential shock hazards or electrical fires. This is particularly important in a workshop or job site environment where contact with moisture or conductive materials may occur.

Using a cord that ensures proper grounding helps protect the user from electrical accidents. It also contributes to the overall safety of the work environment. While other types of cords may serve specific purposes, only the 3-wire cord with ground offers the necessary protection for high-powered tools where the risk of electrical malfunction is significant.
