Electrical drawing
Electrical drawings, sometimes referred to as wiring diagrams, are a type of technical drawing that provide visual representation describing electrical systems or circuits. They are used to explain the design to electricians or other workers who will use them to help install or repair electrical systems.
A set of electrical drawings on a project might include:
- A site plan which shows the location of the building and any external wiring.
- Floor plans which show the positions of electrical systems on each floor.
- Wiring diagrams which show the physical connections and layout of electrical circuits.
- Schedules and other information.
Electrical drawings for buildings tend to include the following details:
- How the electrical wires and other parts of the system are interconnected and switched.
- Where fixtures and other components connect to the system.
- Incoming power lines and their voltage, size, capacity and rating.
- Power transformers and their winding connection and means of grounding.
- The main switches, fused switches and tie breakers.
- Equipment such as batteries, air conditioning, solar panels, generators, and so on, including their voltage and size.
They typically feature complex symbols and annotation to represent and explain components of the system.
