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.

For example, once the electrical designs are complete, they must be built by an electrician. Therefore, it is your responsibility to effectively communicate your design intentions to the electricians through drawings.

Transformers may be fitted with turret tags suitable for soldering and printed circuit board assemblies may have solder pins.

You're permitted to use wiring channels if they're made of a flame-retardant insulating material. If you're working with back-connected control panels, you must provide access doors or swing out panels that swing about a vertical axis. Multiple-device control panels must have terminal blocks or attachment plugs and receptacles to terminate and connect all outgoing control conductors.

Two of the phases are also connected to the transformer to power the logic. The start and stop buttons are at the left of the box (note: normally these are mounted elsewhere, and a separate layout drawing would be needed).

The continuity function measures resistance, and if there is a complete connection the meter will give an audible beep. If there is no continuity your DMM will show “OL” on the display meaning there is an open line. You can use this to test for electrical shorts in wiring or components. I commonly use this function to quickly test for shorted ignition switches and ignition coils.

Electrical equipment uses a wide variety of wire and cable types and it is up to us to be able to correctly identify and use the wires which have been specified. The wrong wire types will cause operational problems and could render the unit unsafe.
