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.
For electricity to flow, there has to be something to push the electrons along. This is called an electromotive force (EMF) . A battery or power outlet creates the electromotive force that makes a current of electrons flow. An electromotive force is better known as a voltage.
