What is the maximum voltage allowed for a branch circuit in dwelling units and guest rooms or guest suites in hotels or motels?

Explanation:
In dwelling units and in guest rooms or guest suites in hotels or motels, the branch circuits for general lighting and receptacles are limited to 120 volts. This matches the common 120/240V service and the voltage at which most household devices are designed to operate, ensuring safety and compatibility. Higher voltages like 208V, 240V, or 480V are used only for specific loads or special circuits and require dedicated wiring and equipment. So the maximum voltage for a typical branch circuit in these spaces is 120 volts.
