Why is there only red black and white wire ceiling and no green?

Each color means a different thing and there are green ones, they are just not as common There should be a bare wire along with the red, black and green wires in the ceiling. It is possible that it was cut off short or tied up to the box somewhere. this is the same as the green wire.


How do you connect timer white and black house wire with red black and white wires?

House wire is "line" Black & White house goes to Black & White of Timer; the "load" (e.g. Pond Pump, etc.) is connected to the Red & White. Specifically, put all 3 whites together (nut or terminal); House (source)(line) Black to Timer Black; and "load" Black to Timer Red. The Red wire is the "Timed" (switched) hot wire.


Light switch has 4 wire colors red and white and green and black which is the hot wire?

You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.


How do you wire a light switch with only black and red wires?

The black wire is typically the hot wire that carries the electrical current, while the red wire is often used as a traveler wire. Connect the black wire to one terminal of the light switch and the red wire to the other terminal. Make sure to turn off the power before wiring the switch to avoid electrical shock.


What is the red wire and what wire does it go with when there are three wires black red and white?

Red, white, and black are standard for a three-way switch (you have two switches that control the same fixture). You should also have a ground wire (copper, unsheathed). The black and red are negative, while the white is positive. It works pretty simply. When the switch is up, the black and white are linked, creating a circuit. When it is down, the red and white are linked. If both switches agree (both are red/white or both are black/white), then the circuit is completed and power flows.
