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.


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.


Does the red wire go where the switch is marked common?

Typically the white wire is "neutral" and colored wires are power. In a light switch, it depends on what the electrician wanted to do. Most use white for common and colored wires for travelers, but don't count on that. Switch legs often are wired a little differently, depending on the electrician. If an electrician is being nice to you he will often put colored tape on a wire to indicate what he is doing, but it's not required. If you have questions about the wiring, contact a qualified electrician to help with the problem.


Ive got red wire and black wire plus earth does red go to L2 or com?

The red wire typically goes to L2, while the black wire goes to L1. The earth wire should be connected to the earth terminal or grounding screw. Make sure to consult the wiring diagram or a professional electrician to ensure the correct and safe connection.


How do you install a doorbell with four wires both having black and red wires?

It depends on what the wires are connected to and where the power supply is located. If the switch is lighted power has to get to the switch for the light. With a lighted switch you have a hot supply side, a neutral and then the wire going to the bell. So if Black 1 and Red 1 are supply voltage you would connect Red 1 to the hot side of switch, Black 1 would go to common as would Black 2. Red 2 would go to Bell side of the switch.

The larger red wires go on the larger brass terminal, and the little guy goes on the terminal marked S1 (also small). Battery power is ALWAYS going through the big red wires...the little wire gets power from the ignition switch when you turn the key to start.
