At what amperage rating is a dedicated circuit typically installed for kitchen refrigerators?

A dedicated circuit for kitchen refrigerators is typically rated at 20 amperes to effectively handle the load requirements of modern refrigerators. This amperage rating accounts for the initial inrush current that occurs when the refrigerator's compressor starts up, alongside the continuous operation needs of the appliance.

Refrigerators, especially those with additional features like ice makers or water dispensers, can have varying power demands, so having a dedicated circuit ensures they operate safely and efficiently without overloading. Additionally, the National Electrical Code (NEC) guidelines recommend that kitchen circuits, especially those dedicated to larger appliances, use a minimum of 20 amperes to ensure they can accommodate such loads.

Selecting a lower amperage, such as 15 amperes, may not provide sufficient capacity for many modern refrigerators, which could lead to tripping breakers or overheating of the circuit. Higher amperage ratings, such as 30 amperes or above, are typically unnecessary for standard refrigerators and may not comply with residential electrical code requirements for this type of appliance.
