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.

When the current is switched on or off, the electro-magnetic field increases and decreases, rapidly causing, in effect, a radio signal. The effect is similar to the crackle that can sometimes be heard on the radio or television when something like a fridge switches on and off. This radiated signal can be picked up by the other wires in the system and cause interference to the normal working voltages in the system

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.

If the screen is to be connected then make it off in the same way as for coaxial cable with a soldered pigtail and a sleeve.

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.

Line diagrams, also called “schematic” or “elementary” diagrams, show the circuits which form the basic operation of the controller. They do not indicate the physical relationships of the various components in the controller. They are an ideal means for troubleshooting a circuit.
By Sylviane Marcelline. Electrical Wiring. Published at Tuesday, January 23rd 2018, 02:21:59 AM. For grounded control circuits, you may use a green (with or without one or more yellow stripes) or a bare conductor to connect the transformer terminal to a grounding terminal on the control panel.
