Final answer:
The nameplate on an appliance displays the amperes required for proper operation and electrical rating information such as voltage and power consumption.
Step-by-step explanation:
The nameplate of an appliance must show two important things: the amperes required for proper operation and the electrical rating information. The amperes required for proper operation indicate the amount of current that the appliance needs to function correctly. This information is crucial for ensuring that the appliance is connected to an electrical circuit with the appropriate current capacity.
In addition to the amperes, the nameplate also contains electrical rating information such as the voltage required for operation, frequency (if applicable), and power consumption. This information helps users understand the requirements and restrictions for safely powering and operating the appliance.
