Yes, it is possible for the amp rating of a breaker and the amperage draw of an appliance to be different values. In fact, it is quite common for the amp rating of a breaker to be higher than the amperage draw of the appliance it is protecting.
Breakers are designed to protect electrical circuits from overcurrent conditions that can lead to overheating, fires, or damage to the electrical system. The amp rating of a breaker indicates the maximum current that it can safely carry without tripping.
On the other hand, the amperage draw of an appliance refers to the amount of current it requires to operate properly. Appliance manufacturers typically specify the amperage or wattage of their products to help users determine the electrical requirements.
Ideally, the amp rating of the breaker should be equal to or slightly higher than the maximum amperage draw of the appliance it is connected to. This ensures that the breaker can handle the normal operating current of the appliance without tripping. However, it is not uncommon to have breakers with higher amp ratings for flexibility or to accommodate potential future additions or changes to the electrical system.
It's important to note that using a breaker with a higher amp rating than the appliance's amperage draw does not mean the appliance will automatically draw more current. The appliance will only draw the amount of current it requires, regardless of the breaker's amp rating. The purpose of the breaker is to protect the circuit by tripping if the current exceeds its rated capacity, preventing electrical hazards.
In summary, while the amp rating of a breaker and the amperage draw of an appliance can be different values, it is crucial to ensure that the breaker's amp rating is equal to or higher than the maximum current the appliance requires for safe operation.
