Should the connection of a grounded conductor to a terminal reverse the designated polarity?

The connection of a grounded conductor to a terminal should not reverse the designated polarity. In electrical systems, it is crucial to maintain the correct polarity throughout to ensure the safety and functionality of the installation. A grounded conductor serves as a return path for current and is typically connected to the ground system to prevent electric shock hazards and to establish a reference point for other conductors in the circuit.

Reversing the designated polarity could lead to improper operation of electrical devices, increased risk of electrical faults, and compromised safety. For instance, connecting ground to the hot terminal could cause shock hazards, as equipment may become live even when they are not intended to be. Proper alignment of conductors according to their designated function ensures compliance with safety standards and enhances the overall reliability of the electrical system.

Maintaining proper polarity is also a fundamental principle outlined in the National Electrical Code (NEC) and similar safety standards, emphasizing the importance of proper connections in residential, commercial, and industrial wiring.
