The electrical drawings describe different aspects of systems and generally, the electrical drawings grouped to the related or similar elements of the different aspects. This will include the following types of drawings in the same set of planes.
Types of drawings
General Supply
These drawings describe the electrical supply of the system and all the sub circuits derived from the main power and what they will feed. In these planes it is common to find items such as transformers, circuit breakers, fuses, magnetic protection (breakers), power supplies, three-phase power conductors etc.
General Supply
Power
In power drawings power elements are shown, typically electric motors. Usually they contain items such as motors, magnetic-thermal protection, fuses, magnetic protection (breakers), contactors (starters), AC drives, servo drives, soft starters, three phase power system etc.
Power
Control
Control drawings describe the system contact logic; sometimes this logic is destined to control the elements shown in drawings of power. Usually they contain elements such as buttons, switches, pilot lights, coils (valves or relays), open or closed contacts (relays or sensors) among others. The figure shows an example of a control diagram.
Control
Inputs/Outputs
In systems containing controllers, input and output drawings are included. In the input drawings can be observed connections from the field to the controller, typically buttons, switches and contacts among others. In the output drawings can be observed connections from the controller to the field, typically coils, and pilot lights among others.
Input
Output
Supply
In these drawings are shown the elements that feed on the sub circuits described in the General Supply drawing, the elements that usually refers this plane are sensors, power supplies, operator interface, processors and others.
Suply
Terminal block
These drawings show a detail of the connection of each set of terminals involved in the system.

Cabinet
On these drawings are shown the distribution of elements in the cabinets.

Network
In the network drawings are shown the connection of the nodes in different networks of the system.

Tremendous issues here. I’m very satisfied to see your post.
Thanks a lot and I’m looking ahead to touch you. Will you please drop me a e-mail?
I have been browsing on-line more than three hours as
of late, yet I never discovered any attention-grabbing article like yours.
It’s beautiful price enough for me. Personally, if all site owners and bloggers made excellent content as you probably did, the
net might be much more helpful than ever before.
