What voltage serves the water heater in Wendy's Restaurant?

In the context of electrical systems, the voltage used for water heaters in commercial settings like a restaurant typically aligns with standard practices for equipment that requires a significant amount of power but isn't particularly high-demand like industrial machinery.

Water heaters, especially those used in restaurants, often require voltages that are efficient for heating applications while still suitable for the circuit design and safety protocols. A voltage of 120V in a single-phase configuration is more common for smaller, residential-type water heaters or specific low-load applications in commercial installations where high capacity isn't necessary.

The choice of 120V implies the need for a standard outlet configuration that could simplify installation and wiring, especially in a restaurant environment where multiple outlets may be utilized for various kitchen equipment. Although higher voltages like 208V or 240V are often employed for larger heating elements or industrial-grade water heaters due to their ability to provide more power in a smaller current, smaller heating applications can effectively operate at 120V.

Choosing a higher voltage such as 480V or even 208V and 240V typically correlates with machinery that requires more robust electrical service and infrastructure, which may not align with Wendy's typical operational needs for a water heater. Thus, the selection of 120V for
