What color designation identifies a terminal intended for connection with a grounded conductor?

The color designation that identifies a terminal intended for connection with a grounded conductor is white. This designation is based on electrical code standards which specify that white or gray insulation is used for grounded conductors in electrical wiring systems. The grounded conductor, often referred to as the neutral wire, is essential for providing a return path for electrical current and is crucial for ensuring safety and proper operation of electrical systems.

Using white for grounded conductors helps to prevent confusion and ensures that anyone working on or inspecting electrical installations can readily identify which wire is meant to be grounded. Other colors, such as black, red, or blue, typically indicate ungrounded conductors or hot wires, which carry current but are not meant to be connected to grounding systems. This standardized color-coding is vital for electrical safety and compliance with the National Electrical Code (NEC).
