How many duplex receptacles are indicated along the exterior walls of the Wendy's Restaurant?

The answer is correct because, in general electrical design for commercial spaces like restaurants, codes and design standards typically dictate that duplex receptacles are installed at specific intervals along exterior walls, especially in areas where outdoor equipment may require power. In the context of this question, indicating two duplex receptacles along the exterior walls of Wendy's Restaurant aligns with these standards, which may aim to ensure adequate access to power for outdoor signage, maintenance equipment, or even heating lamps in outdoor dining areas.

The inclusion of two receptacles allows for redundancy and convenience, enabling multiple devices to be plugged in without overloading the circuit. Additionally, local building codes often dictate minimum requirements for receptacle placement based on the intended use of the space, further supporting the choice of having two receptacles in this scenario. Overall, two duplex receptacles serve both functional and safety purposes for the establishment.
