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.
When electric charges move in a wire, we say that an electric current flows in the wire. It's like the way a current of water flows in a river. For an electric current to flow, we need two things: something to make the electricity flow, such as a battery or power pack. a complete path for the current to flow in.
