Ground Symbols; Earth Ground: Used for zero potential reference and electrical shock protection. Chassis Ground: Connected to the chassis of the circuit: Digital mon Ground : Resistor Symbols; Resistor (IEEE) Resistor reduces the current flow. Resistor (IEC) Potentiometer (IEEE) Adjustable resistor has 3 terminals. Potentiometer (IEC)
Wiring diagrams use simplified symbols to represent switches, lights, outlets, etc. Here is a standard wiring symbol legend showing a detailed documentation of common symbols that are used in wiring diagrams, home wiring plans, and electrical wiring blueprints.
Symbols of Lines, Wires, Cables and Electrical Conductors. The power lines, wires, cables, conductors... are materials that conduct electricity easily, such as certain metals. They are also electrically conductive electrolyte and ionized gases.
The Grounding Symbols. Identifying the ground terminal is critical to ensuring the products you design can be properly used and serviced in a safe manner. The actual symbols used to indicate ground terminals are found in IEC 60417 Graphical symbols for use on equipment (Figure 1).
A copper wire connects the ground rod to the main electrical distribution box (or panel). This symbol belongs on your home wiring plan. It can also go on a schematic diagram to indicate the Earth ground of an antenna system. You may also notice that your telephone and or cable company also uses this rod as a ground for their systems.
GROUND SYMBOLS: Ground It is equivalent to theoretical 0V and is used as zero potential reference. It is the potential of perfectly conducting earth. Signal Ground It is a reference point from which the signal is measured. There may be several signal grounds in a circuit due to the voltage drops in a circuit. Chassis Ground
The earth ground symbol is, unfortunately, used in many applications in electronics and electrical engineering, often meaning different things to different people, so it may be a bit confusing to some beginners. For instance, the earth ground symbol is also used as a common ground symbol or a 0V reference.
