Does a conductor with white or gray insulation at a circuit termination where the circuit is a maximum of 50 volts need to be grounded?

A conductor with white or gray insulation is specifically designated for certain uses under the National Electrical Code (NEC). In general, white or gray insulation indicates that the conductor is neutral. When dealing with circuits operating at a maximum of 50 volts, whether it needs to be grounded can depend on various factors, including safety standards and the purpose of the circuit.

In this scenario, grounding a conductor is crucial in ensuring that any fault current can be safely redirected to the ground, rather than posing a risk of electric shock or equipment damage. While the NEC does have provisions that dictate whether certain conductors must be grounded, the broader safety practices would dictate that any conductor that has white or gray insulation should be treated with caution, as it is often associated with the return path of current.

Thus, given that the question specifies a conductor with white or gray insulation, the rule that mandates grounding them helps ensure compliance with established safety standards and reduces the risks associated with ungrounded systems. This reinforces the importance of adhering to grounding practices regardless of the voltage level when dealing with neutral conductors.
