Some components and symbols of wiring diagram are: Capacitor, used to store electric charge. Toggle Switch, stops the flow of current when open. Push Button Switch, momentarily allows current flow when button is pushed in, breaks current when released. Battery, stores electric charge and generates a constant voltage .Resistor, restricts current flow. Ground wire, used for protection. Circuit breaker, used to protect a circuit from an overload of current. Inductor, a coil that generates a magnetic field. Antenna, transmits and receives radio waves. Surge protector, used to protect a circuit from a spike in voltage. Lamp, generates light when current flows through. Diode, allows current to flow in one direction indicated by an arrowhead or triangle on the wire. Microphone, converts sound into electrical signal. Electrical motor. Transformer, changes AC voltage from high to low or vice versa. Headphone. Thermostat. Electrical outlet. Junction box.
Generally, single conductor building wire in small sizes is solid wire, since the wiring is not required to be very flexible. Building wire conductors larger than 10 AWG (or about 6 mm²) are stranded for flexibility during installation, but are not sufficiently pliable to use as appliance cord.
Most of wiring diagram software has a unique feature for electrical cabling: the wiring diagram or single line diagram, allowing a simplified representation of an electrical cabling installation in pre-study phase.
Copper sheathed mineral insulated cables at a panel board. For some industrial uses in steel mills and similar hot environments, no organic material gives satisfactory service. Cables insulated with compressed mica flakes are sometimes used. Another form of high-temperature cable is a mineral insulated cable, with individual conductors placed within a copper tube and the space filled with magnesium oxide powder. The whole assembly is drawn down to smaller sizes, thereby compressing the powder. Such cables have a certified fire resistance rating and are more costly than non-fire rated cable. They have little flexibility and behave more like rigid conduit rather than flexible cables.
