What maximum amperage can a branch circuit serving a kitchen appliance be rated for?

• A. 10 amperes
• B. 15 amperes
• C. 20 amperes
• D. 30 amperes

Answer: (C)

The correct answer is that a branch circuit serving a kitchen appliance can be rated for a maximum of 20 amperes. In residential wiring, kitchen circuits are often required to support a range of appliances that may have higher amperage demands for functionality and safety. To provide adequate power supply and avoid overloading the circuit, the National Electrical Code (NEC) typically stipulates that kitchen circuits are rated at 15 or 20 amperes. However, 20-amp circuits are most commonly used for countertop receptacles and appliances, as they can handle higher wattage loads, such as toasters, blenders, and microwaves, which are common in kitchen settings. Voltage drop, appliance usage, and the potential number of items drawing power simultaneously must be considered. A 20-amp circuit provides more flexibility and reduces the risk of tripping breakers during heavy appliance use. Thus, it is the standard for accommodating most kitchen appliance requirements safely and effectively.
