What are the basics of wiring?
Most residential service includes three wires: two cables carrying 120 volts each (for a total of 240 volts) and one grounded neutral wire. If the cables are hung overhead, they are collectively called a service drop. If they are routed underground, they are known as a service lateral.
Which color wires go together?
The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active.

How do wiring diagrams work?
It shows the components of the circuit as simplified shapes, and how to make the connections between the devices. A wiring diagram usually gives more information about the relative position and arrangement of devices and terminals on the devices.
What are the three types of electrical diagrams?
Types of Electrical Diagrams or Schematics
There are three ways to show electrical circuits. They are wiring, schematic, and pictorial diagrams.
How are wiring diagrams organized?
Unlike a pictorial diagram, a wiring diagram uses abstract or simplified shapes and lines to show components. Pictorial diagrams are often photos with labels or highly-detailed drawings of the physical components.
What is a 3 line drawing?
Three-line diagrams expand on the single-line by providing a basic visual guide for actual feeder cabling, instrument transformer connections, and protective devices. These drawings show how phases are wired and specific winding configurations without regard for their physical location.
What electronic diagram is easier to understand explain?

1), often called a ladder diagram, is intended to be the simplest form of an electrical circuit. This diagram shows the circuit components on horizontal lines without regard to their physical location. It is used for troubleshooting because it is easy to understand the operation of the circuit.

What does COM mean in wiring diagram?
COM is the common connection for relay or transistor outputs; essentially when the output is activated, the PLC will energize the relay or transistor, effectively connecting the NO (normally open) pin to the COM (common) pin. Some PLCs have form-C contacts, which would have NO, COM and NC (normally closed) contacts.
What is Com and L1 in switch?
The faceplate of a single, one-way switch has two terminals: “L1” is the terminal to which the neutral core wire is attached – the blue wire (traditionally black, before the change). “COM” or “Common” is the terminal to which the live core wire is attached – this is the brown wire (formerly red).
What does L1 L2 and COM mean?
The single direction plane switch has two L1 terminals, the terminal to which the neutral cable is connected – the blue cable (traditional black, before changing). COM or Common is the terminal to which the live core cable is connected – this is the brown cable (red era).
