K-LOK 400A Grey

K-LOK 400A in grey housing is used in the North American 277/480V high-voltage color code as Neutral (N). Grey identifies the higher-voltage neutral where the standard 120/208V White is replaced by Grey to avoid confusion between voltage systems. The color is purely visual phase identification, mating mechanics are identical across all K-LOK 400A colors.
