From Wikipedia
For the larger Multipole design, each color is keyed so as to mate only with a like colored connector, and Anderson publishes a list of recommended voltages for each color:
- 12 V: Yellow
- 18 V: Orange
- 24 V: Red
- Used by Warn for its 12 V winches (should have used yellow multipole)
- Used by Tripp-Lite for some of its 24 V external UPS battery packs
- 36 V: Gray
- Used by Tripp-Lite for some of its 38 V external UPS battery packs
- Used by APC for some of its 24 V external UPS battery packs (should have used red multipole)
- 48 V: Blue
- Used by Tripp-Lite and APC for its 48 V external UPS battery packs
- 72 V: Green
- 80 V: Black
- 96 V: Brown
- 120 V: Purple
- 144 V: White
Some manufacturers have ignored this color coding recommendation. One should always test the connection with a voltmeter if unsure. For example, winch manufacturer Warn uses a red housing for its winches, even though they are powered by 12 V DC, not 24 V DC.
