If a circuit is wired in parallel with a supply voltage of 120 volts, what voltage rating is required for each load?

In a parallel circuit, all loads receive the same supply voltage. If the circuit is wired to a supply voltage of 120 volts, it means that each load within that parallel circuit will also experience the same voltage of 120 volts. Therefore, the voltage rating required for each load must match the supply voltage to ensure safe operation and compliance with electrical standards.

Selecting a voltage rating lower than the supply voltage could result in the load being overloaded or failing to operate correctly. Conversely, a higher rating than necessary is not a concern for operation but is not effective for ensuring compatibility with the circuit's supply. The standard practice in parallel wiring is to use loads rated for the same voltage as the supply to avoid any potential hazards or malfunctions.
