A qualifying symbol is graphics or text added to the basic outline of a device’s logic symbol to describe the physical or logical characteristics of the device. 26 libraries of the Electrical Engineering Solution of ConceptDraw PRO make your electrical diagramming simple, efficient, and effective....
Symbol Name Meaning Grounding Indicates the position for connecting the protective earthing (PE) cable. Height label The equipment is high. You may need to use tools to facilitate operation, such as an insulation stool or a step ladder. Box No. label Displays the equipment box No. ...
Note the drafting error in the lower right, where the power-supply "ground" is a different symbol from that used in the rest of the circuit. Since the cathodes of all tubes are returned to the normal ground signal, that must be the negative end of the power supply as well. ...
that is, it is positive at the same time or negative at the same time, and the polarity is called the same polarity end or the same name end. The symbol "*", "-" or "." indicates. (It can also be understood as the direction relationship between primary current and secondary current...
In the diagram above, taking an installation without an isolation transformer, the device has an earth fault (for example a live conductor has shorted to the chassis). Since Neutral and Earth are bonded in the consumer unit the system sees this as a short circuit and so a large current wil...
