Which type of circuit is required to serve receptacle outlets in detached garages?

In the context of electrical installations, a detached garage is often considered a separate structure and therefore has specific requirements for electrical circuits. A 20 Amp branch circuit is typically required to serve receptacle outlets in these types of areas. This is due to several factors:

1. Load Capacity: A 20 Amp branch circuit can support a wider variety of appliances and tools that may be used in a garage setting, including power tools, electric lawn equipment, and other devices. The additional amperage helps ensure that the circuit can handle devices that have higher current draw.

2. Code Requirements: Electrical codes, including the National Electrical Code (NEC), often specify circuit capacities based on the type of load and the location of the installation. The requirement for a 20 Amp circuit for receptacles in detached structures aligns with these safety and functionality standards.

3. Safety: Using a circuit with appropriate ratings helps to prevent potential hazards like overheating and tripping. It ensures that users can operate devices without risk of overload which could lead to circuit failure or fire.

Circuit configurations with lower amperage, such as 15 Amps, 10 Amps, or higher like 30 Amps, would not provide the necessary capacity for robust electrical
