What is the color code for 120 volt?
For ordinary 120-volt circuits, each cable will have a white “neutral” wire, grounded at the service disconnect switch. Most cables will also have a bare copper or green equipment ground wire, to protect us from electrocution by faulty appliances.
What color is 220 wiring?
Red wires
Red wires are secondary wires in 220-volt systems. They are often used in switch legs and to connect smoke detectors to home systems, particularly to power the triggers that set all the detectors off at once. Red wires can be connected to each other.
