There are many guidelines addressed in the NFPA 70 that make working with electrical hazards safer for employees. Here are some of the main areas of protection addressed: grounding of wires, fire alarm equipment, physical protection, abandoned supply circuits, communications equipment, temperature ratings, special requirements for information technology equipment room, among many other important guidelines.
Electric current is electric charge in motion, such as the flow of electrons through a wire. Electric current is electric charge in motion, such as the flow of electrons through a wire.
Video: What is Electric Current? Like a river current is the flow water of water molecules, electrical current is the flow of charged particles. In this lesson, we're going to explore what electrical current is, what causes it, and that, unlike a water current, electrical current doesn't always flow in one direction.
