1. 1

2. 2

3. 3

4. 4

The correct answer is: 2

In residential electrical installations, particularly within kitchen and dining areas, the National Electrical Code (NEC) stipulates specific requirements for branch circuits to ensure safety and functionality. The regulation requires a minimum of two 20 ampere rated branch circuits to serve all wall and floor receptacle outlets in these areas. The reasoning behind this requirement is to provide sufficient capacity for the various appliances and equipment commonly used in kitchens and dining spaces, such as microwaves, toasters, coffee makers, and other devices that may draw significant power. By mandating at least two circuits, the code helps prevent overloading a single circuit, thereby reducing the risk of tripped breakers or potential fire hazards. In contrast, lower numbers of circuits would not adequately support the simultaneous use of multiple high-demand appliances, leading to an increased risk of electrical issues. This requirement is part of a broader safety framework intended to enhance electrical reliability and user safety in residential settings.
