Red, Gray and Blue housings - what's the difference?
Housings are color-keyed. This means gray housings will only plug into gray housings, not red or blue housings. The color key feature makes it possible for you to differentiate voltages of your electrical circuits.
The industry has established guidelines for the colors and what voltages they should be used with to formulate a standard for the safety of all workers and to safeguard equipment. Here are those guidelines:
| Voltage | Housing |
| 12Volt | Yellow* |
| 18 Volt | Orange* |
| 24Volt | Red |
| 36Volt | Gray |
| 48Volt | Blue |
| 72Volt | Green* |
* denotes colors that must be special ordered
