What is shown on a building electrical plan?
The electrical plan is sometimes called as electrical drawing or wiring diagram. It is a type of technical drawing that delivers visual representation and describes circuits and electrical systems. It consists of electrical symbols and lines that showcase the engineer’s electrical design to its clients.
What are electrical signs and symbols?
Electrical signs and symbols provide workers and others with information on electrical hazards and instructions on preventing harm. Labels, such as those used in PAT testing, inform people that electrical equipment and appliances are safe to use or not.
