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.
Charge and current. Electric current is the rate of flow of electric charge. No current can flow if the circuit is broken - for example, when a switch is open. An electric current flows when electrons move through a conductor, such as a metal wire. Metals are good conductors of electricity.
