Ieee Basic Electrical Symbols
The most common symbol used to represent a circuit breaker is a large red circle with a small black line. This indicates a standard general-purpose circuit breaker, which is rated for currents up to 300 amps. The most common types of circuit breakers include thermal-magnetic, miniature, and high-voltage. Thermal-magnetic breakers are used in.

Two-pole breakers can be either slash or straight voltage-rated, whereas 3-pole breakers are all straight voltage-rated. Temperature Rating [Sec. 110.14(C)]. You must size conductors to the lowest temperature rating marking on the breaker. For all practical purposes, conductors for circuit breakers are sized based on the 75°C column of Table.

Circuit Symbols 101. Circuit symbols are used in circuit diagrams which show how a circuit is connected together. The actual layout of the components is usually quite different from the circuit diagram. To build a circuit you need a different diagram showing the layout of the parts on stripboard or printed circuit board.
