Final answer:
A technician must be certified to work on small appliances post-November 14, 1994, to ensure safety regarding electrical components. The certification aligns with the technician's knowledge of amperages, circuit breakers, fuses, and preventing electrical shocks. The type of certification, such as Type I, Type II, or Universal, indicates the technician's scope of expertise.
Step-by-step explanation:
To work on small appliances after November 14, 1994, a technician must be certified because handling electrical components and circuits requires knowledge of safety features and potential hazards. Certification ensures technicians have the necessary skills to mitigate risks of electrical shock and thermal overload. The circuit breakers or fuses protect against thermal overload, and the protective casing around appliances like toasters and refrigerators serves to prevent electrical contact. Most appliances are rated in amperes, also known as amps, which correlates to the capacity of fuses and circuit breakers used to safeguard electrical circuits.
Working on small appliances often requires minimal specialized skills and education, typically involving the operation of specific types of equipment. The workers in this field usually earn an hourly wage and must understand the basic functions of appliances and their electrical requirements. Proper certification may correspond to the technician's proficiency level, such as Type I, Type II, or Universal, indicating their qualifications to manage different appliances and situations.
