Once you do, you are able to read diagrams quickly, and can often understand a circuit at a glance. The more you work with both line and wiring diagrams, the better you will become in analyzing them.

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 highly disturbing device (variable speed drive, frequency converter, etc.) will have less radiation in the panel if it is “encapsulated” in a small, electromagnetically sealed, unpainted metal enclosure.

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!
By Charline Rodrigue. Electrical Wiring. Published at Saturday, February 03rd 2018, 02:17:12 AM. Electrical symbols are used on home electrical wiring plans in order to show the location, control point(s), and type of electrical devices required at those locations. These symbols, which are drawn on top of the floor plan, show lighting outlets, receptacle outlets, special purpose outlets, fan outlets and switches.

Ensure that identification tags and cable markers are legible, marked with a permanent ink and suitable for the environment where the panel is to be used. They should also correspond with those shown in the machine drawings and instruction or service documentation.
By Claudie Ulysse. Electrical Wiring. Published at Friday, February 02nd 2018, 12:57:01 PM. Soldered connections should be made only to terminals suitable for that purpose. Transformers may be fitted with turret tags suitable for soldering and printed circuit board assemblies may have solder pins.
