Red, Gray and Blue Housings - What's the Difference?
All housings are color keyed. This means gray housings will only plug
into gray housings. Gray housing won't plug into red or blue housings.
Similarly, the color key feature makes it possible for you to
differentiate voltages of your electrical circuits. For example, you do
not want to plug a 36 volt battery pack into a 48 volt charger. Color
keying your wiring will help to prevent expensive and dangerous damage.
Gray housings are by far the most commonly used color. People who have
only one voltage in their work environment tend to use gray housings no
matter what the voltage is. However, if you have multiple voltages in
your work environment, we would strongly recommend that you follow the
industry color code guidelines listed below.
