Electrical drawings are technical documents that depict and notate designs for electrical systems. Workers use these documents to install systems onsite. In electrical drawings, every type of component and connection has its own specialised symbol – and every detail matters. A wiring diagram is a simple visual representation of the physical connections and physical layout of an electrical system or circuit. It shows how the electrical wires are interconnected and can also show where fixtures and components may be connected to the system.
Electrical designs are responsible for the building power switch board, Wiring, Fire alarm, lightning as well as lighting system.Electrical Design is a field of engineering that generally deals with the study and application of Electricity, electronics, and electromagnetism.
