Class 1 circuits typically operate from greater voltage and current levels than those of Class 2 or 3 circuits.

Question

Quizplus · Accepted Answer

Class 1 circuits are defined as those that operate at power levels exceeding those of Class 2 and Class 3 circuits. They typically supply power to equipment such as motors, lighting systems, and other high-power devices. Class 2 and Class 3 circuits, on the other hand, are designed to operate at lower voltage and power levels and are used for applications such as low-voltage lighting, audio systems, and small electronic devices.
