Figure 6.116 shows some of the basic symbols that are used to designate fuses on schematic diagrams. 6.12.1.9 Circuit Breakers A circuit breaker is an electric device (similar to a switch) that, like a fuse, interrupts an electric current in a circuit when the current becomes too high.

Electrical circuit breakers are typically not found in semiconductor chips or small systems; the both fuses and circuit breakers can be integrated into a common system.

Since the rules state that our generators must have air The appliance is said to be double insulated and is marked with the symbol shown. Residual current device (RCD) A residual current device (RCD) responds more rapidly than a fuse or a circuit breaker if a fault occurs. It can detect a very small change in the current in the live and neutral wires and breaks the circuit immediately. A current difference of as little as 30mA can be detected, so the circuit is broken before a person could receive a fatal electric shock. RCDs are used

Most can sense a high current condition, disconnect the circuit temporarily, and then reset itself. The circuit breaker will reconnect the circuit again after it cools down and if current draw returns to normal.

Note that a large symbol may indicate a circuit breaker with a higher a great many relay symbols which an electronic draftsman is called on to use from time to time. THE CIRCUIT BREAKER The circuit breaker, as its name implies, is a protective device which opens a circuit automatically (based on a predetermined condition) to protect the circuit's components. It should be noted that a fuse performs an identical function but is destroyed in the process, whereas the circuit breaker need only be closed again. The basic circuit breaker symbol is shown in Fig substation

the.closing or tripping of a circuitbreaker is achieved by the operation of an interposing relay, as the operation of a circuitbreaker is usually by means of a ll0 V battery. The interposing relays are selected in pairs by means of a rotary line switch associated with a particular group. At the control room each circuitbreaker is represented by a 'symbol discrepancy' key. The symbol key is rotated through 90 deg to originate a selection. The symbol lamp glows to indicate that the
