What are the Meanings of Electrical Drawing?

The first step that we are going to take is to know the etymological origin of the two words that give shape to the term electrical drawing that concerns us:

-Drawing comes from French, exactly from the verb “déboissier”, which can be translated as “to draw”.

-Electric, meanwhile, derives from the Greek as it is the result of the sum of two clearly differentiated components of that language: the noun “élektron”, which means “amber”, and the suffix “-ikos”, which is used to indicate “relative to”. This term must be stated that it was coined by the British physicist William Gilbert (1544 – 1603).

A drawing is a trace that is made on a surface. Usually it is an image or representation of something. Electric, on the other hand, is that related to electricity: the force manifested by the rejection or attraction between particles that have a charge, and the form of energy that is based on said force.

An electrical drawing makes it possible to represent an electrical installation.

What is an electrical drawing

It is called an electrical drawing to the diagram that is made to represent an electrical installation. These representations use symbols to refer to switches, circuit lines and the rest of the components of this type of installation.

There are many symbols that appear in a drawing of this type and that you have to know. Specifically, there are two kinds of them: the electronic ones, such as the resistor and the capacitor, and the electrical ones. Among the latter are the light bulb, the motor, the voltmeter, the battery, the battery, the switch…

Among the components that should not be missing in any electrical drawing are the meter box, the switches, the main board, the power outlet, the circuit line, the lamp outlets or the connections, for example.

Electrical drawings use symbols.

Technical graphic representation

Electrical drawings are part of the set of technical drawings, which are graphic representations whose purpose is to provide useful information to analyze, design, build and/or maintain some type of installation, infrastructure or work. Architectural drawing, electronic drawing and mechanical drawing are other technical drawings.

When making an electrical drawing or any other technical drawing, you must bear in mind that you have to resort to a wide variety of line classes, among which the guide lines, the symmetry lines, the hidden line, the break line stand out., center or dimension, for example.

Utility of electrical drawing

An electrical drawing can be useful to diagram or remodel the electrical installation of a house, a company or an industry. It is also linked to motors and other electrical devices. Its preparation must be developed by an electrical engineer since the author must have the necessary technical knowledge to carry out the representation in question.

Take the case of building a house. In addition to the work of the architect regarding the material structure of the construction (walls, ceiling, etc.), a specialist will be needed to develop the electrical drawing of the facilities to define where there will be outlets, where the cables and other details specifically related to electricity.
