Brown blue and green stripe wiring is actually more common around the world than our black white and green.

120 volt fan wiring red wire black white blue. If there is an extra red wire you should get a reading of 120 volts when you touch the terminals of the tester to the red and white wires. For wires that will be 120 208 or 240 volts the following wiring color standards are used. Red or orange can also be used as a second switched power wire in a 120-volt application.
