Final answer:
Breakers are safer than fuses because they have faster response times and can be reset. They open the circuit to prevent thermal hazards when an excessive current is detected. Circuit breakers are rated in amperes and protect residents and appliances from damage caused by large currents.
Step-by-step explanation:
Breakers are safer than fuses because they have faster response times and can be reset. When a circuit breaker detects an excessive current, it opens the circuit to prevent thermal hazards. Fuses, on the other hand, permanently break the circuit when overheated by an excessive current.
Circuit breakers in a home are rated in amperes and are used to protect residents and appliances from damage due to large currents. The rating of a circuit breaker indicates the maximum current it can handle. For example, a 15-amp circuit breaker may be used to protect several outlets in the living room, while a 20-amp circuit breaker may be used to protect the refrigerator in the kitchen.
In addition to circuit breakers, other electrical safety devices such as ground fault circuit interrupters (GFCIs) are used in bathrooms and kitchens to quickly respond to changes in current and prevent electric shocks.
