Why is it important to know how do you interpret electrical diagrams and plans?
Firstly, good electricians (who can read circuit diagrams) consider diagrams as part of their working conditions and will be frustrated very quickly if they are expected to work in the dark, without proper diagrams. You therefore stand a better chance of retaining a good electrician if your diagrams are in good order.15 août 2017
Why is it important to interpret a wiring diagram?

How important are the electrical signs and symbol?
An electrical symbol is a visual symbol that represents a particular type of electrical component in electronic devices such as wires,batteries etc. The electrical symbols are very important especially when fixing electrical appliances because it tells you where the wire of neutral and live go.
Why do we use symbols to show electrical components?
An electrical schematic diagram, or circuit diagram, is a drawing that shows the connections and components in an electrical circuit. … It makes it easier to understand how to build a particular circuit. We use symbols for the components in circuit diagrams, because it’s quicker and requires less artistic skill.

What is an electrical wiring diagram?
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.
How do you read a wire?
The thicker a wire, the lower its number; for instance 12-gauge wire is thicker than 14-gauge. Cable refers to two or more wires encased in a protective sheathing. Cable packaging indicates the gauge and number of wires. For example “12/2 WG” means two (black and white) 12-gauge wires plus a ground wire.23 oct. 2017

What is the difference between wiring diagram and electrical diagram?
A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. … A pictorial diagram would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.
