Ceiling fans can use two hot wires. While wires designated as hot black or red insulated wires carry power from the service panel breaker box to the device neutral wires carry power back to the service panel.
Wiring Colours Electrical Cable Colour Coding Standards
Can red and black wires go together. While wires in these colors carry power they are not used in typical outlet wiring. When wiring a panel or installing breakers identify wire color to insure that when you are sharing the neutral the black is on phase 1 and red wire on phase 2. Depending on how they are connected at the switches depends on which one you connect the fan or the light at the ceiling. If you have the additional toggle switch connect the two black wires together with an orange wire connector and then match the blue wire and the. One is for the fan and the other is for the light. If you see a red wire spliced together with a black one in a 120 volt outlet its probably because the outlet is powered by a wall switch.
In addition red wires are used to connect hardwired smoke detectors to the homes power system. In 220 volt circuits red wires are the secondary live wires. In some jurisdictions all wire colors are specified in legal documents. Its possible to link two red wires together or a red wire to a black wire. Typically a ceiling fan is wired so the fan motor has power all the time by the black wire and the light of the ceiling fan is controlled by the wall switch through the red wire. In that case local custom dictates the.
Blue and yellow electrical wires. Wiring for ac and dc power distribution branch circuits are color coded for identification of individual wires. Like black wires they can also be used in some types of switch legs. When there is a separate red and black wire in the ceiling fan box this usually means that one of the wires is controlled by a wall switch. Twist a yellow wire connector to all three wires. If you have two switches to control the fan then black and red are the two wires from the two switches.
Certain switch loop configurations require a three conductor wire the extra wire is needed to complete the circuit at the switch. If not color all phase 2 wires with. Connect the red wire coming from the outlet to the bottom switch terminal and now the lower receptacle on the split tab outlet will get power only when the switch is on. Connect the black jumper wire to the top terminal screw on the switch and now both the switch and the top receptacle in the split tab outlet have power. In other jurisdictions only a few conductor colors are so codified. Thus both hot and neutral wires have the potential to shock and injure you.
