Cam-Lok® Connector Colors: What Do They Mean?

When browsing through our Cam-Lok® power cables, you may notice the connectors come in various colors. But what do the colors indicate?

The colors actually correspond to the different functions of the terminals. These different color indications are important, because the user should always verify the correct phase in relation to color coordination. The common American colors are green, white, black, red, and blue.

Are the Colors Determined by NEC?

It’s a common misconception that the colors of the Cam-Lok® connectors are established by the National Electric Code (NEC), but this isn’t the case. The NEC only requires that green must be used solely for the Equipment Grounding Conductor, and that white or grey are used for the Neutral conductor. These colors may not be used for any other purpose, nor may their purpose use a different color. Aside from these exceptions, the colors are not specified by the NEC for general power distribution. It’s important to note that black was originally used to indicate neutral and is now a phase color. Blue was previously used to denote a phase, but is now used to denote a neutral.
