Class 2 circuit conductors must maintain a minimum separation of how much when introduced into enclosures with power conductors?

The correct answer is a minimum separation of ¼ inch when Class 2 circuit conductors are introduced into enclosures with power conductors. This separation helps reduce the risk of electrical interference and potential faults that could occur if Class 2 conductors were to come into contact with higher-voltage power conductors. Maintaining this distance ensures that the insulation integrity of Class 2 conductors is upheld, which is crucial for their proper function and safety.

The specified separation applies to ensure compliance with safety standards and regulations, which are designed to protect both the equipment and the users from electrical hazards. In practice, these standards help in minimizing the potential for overheating and shielding Class 2 circuits from electromagnetic interference that could negatively affect performance.
