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.
Electric and magnetic fields are examples of energy transmission. Electricity is the result of a moving electric field caused by the movement of. electrons. A moving electric field causes a change in the magnetic field. The. relationship between an electric field and magnetic field shall be investigated.
