These conductors must be yellow throughout the entire circuit, including wiring in the control panel and the external field wiring. • White or natural gray represents a grounded circuit conductor. • White with blue stripe represents a grounded DC current-carrying circuit conductor. International and European standards require you to use light blue for the neutral conductor. • White with yellow stripe represents grounded AC current-carrying control circuit conductors that remain energized when the disconnecting means is in the OFF position. For additional circuits powered from different sources that remain energized when the main disconnecting means is in the OFF position, you must use striping colors other than green, yellow or blue to uniquely identify the grounded conductors.

A receptacle outlet is one in which one or more receptacles are installed for the purpose of attaching “plug and cord-connected” type devices, and a lighting outlet is one intended for a direct-wired connection to a lamp holder, luminaire (lighting fixture) or ceiling fan.

Wiring diagrams, sometimes called “main” or “construction” diagrams, show the actual connection points for the wires to the components and terminals of the controller.

The control panel may be isolated but the lamp will require power so that the engineer can see while working on it.

Figure 5 below shows a schematic diagram for a PLC based motor control system, similar to the previous motor control example.

Dashed lines are drawn between the symbols to denote which switches control specific lights or receptacles. There are quite a few symbols used to represent the devices used in home electrical wiring but some of them are very similar, so care should be used when working with them!

Before entering your home, electricity passes through a watt-hour meter which measures the amount of electricity used.
