Which class of circuit permits a higher voltage than a Class 2 circuit?

The correct class of circuit that permits a higher voltage than a Class 2 circuit is Class 1. Class 1 circuits can operate with a voltage up to 600 volts and are typically utilized in applications where higher power is required. This may include fire alarm systems, security systems, and other low voltage applications that still need a robust power supply.

In contrast, Class 2 circuits are limited to a maximum of 60 volts and are designed for lower power applications, ensuring safe operation without the risk of severe electrical shocks. The distinction between Class 1 and Class 2 is significant, as it affects how installations must be designed with regards to safety, grounding, and wiring practices.

Class 3 circuits also operate at a lower voltage than Class 1, similar to Class 2, but are primarily intended for specific applications and have a similar maximum voltage limitation. Class 4 is not a standard designation in the context of low voltage systems as used in these classifications.

Understanding these classifications is essential for professionals working in low voltage communication systems, as they directly impact the design and implementation of various electrical systems within residential and commercial settings.
