What is the common thread of the ceiling?
2 answers. The red wire is the ungrounded (thermal) conductor of one switch, and the black wire is the ungrounded (thermal) conductor of the other switch. In the original installation, one switch activates the red wire and turns on the fan, while the other activates the black light.Similarly, you may be wondering what the thread is for?
The red electrical wire indicates the secondary power wires on a 220 volt circuit used in some types of switches and in the interconnection between smoke detectors connected to the electrical system. You can connect a red wire to another red wire or to a black wire.Second, can I connect the red and black wires?
In 220 volt circuits, the red wires are the secondary power cables. Like black wires, they can be used in some types of switch legs. You can connect two red wires or one red wire to one black wire.So we can also ask ourselves, what is the common thread?
The answer is that the red wire is the hot wire of the switch itself. You connect the device to a junction box where the Buku cables meet. Hang the white on the white, the earth on the earth and the RED on the BLACK wires of the lamp.How do I connect a ceiling fan with a red wire?
- Connect the green wire to the ground wire (copper / cable only).
- Connect the white wires together and secure them with a cable clamp.
- Connect the red wire from the ceiling to the black wire from the light kit and the black wire from the ceiling to the black wire from the fan.
- Reconnect the wires to the box.
