If what you are referring, is the blue Neutral wire in the UK/Ireland, it eventually connects to ground or earth potential at some point on its way to the power station. It is usually at or near zero volts potential but may not always be so.

In the US where do the blue red green and white wires on a fan go to when the ceiling has red black bare copper and white wires?

Black to Black - Black from the ceiling is a hot wire and should be switched Red to Blue - Red wire is another hot wire and should also be switched White to White - White from the ceiling is the neutral and should not be switched. Your wall should have two switches, one will control the red wire, one will control the black wire. If you wire your fan as above, one switch will turn the fan on, the other will turn the light of the fan on.


When you connect earth wire in ceiling light does not work when connecting earth from light direct to earth wire coming from ceiling trips out when take earth wire out light works?

By earth wire I am assuming you mean the bare wire and that a black and white wire are connected to the light. If when you connect the earth wire and breaker trips then there is a short between black and earth. It could be a bad ground connection, an internal short in the light fixture where black wire "hot" is connected to metal on the fixture through a nick in wire.


How do you rewire a wall switch to control both ceiling fan and light. The switch currently furns the fan on and off but the light has to be controlled with a pull chain?

Open up the ceiling box and disconnect the blue wire coming from the light and connect it to the black wire coming from the fan. Be sure and put a wire nut on the wire where the light was connected before you removed it. The wall switch is controlling power to the wire where the fan is connected so when you connect the blue fan wire to that connection you will be sending power to both the fan and light from the wall switch.


How do you connect a new ceilling fan to an old electrical connection which inclue a pipe and two thick electrical wires one black and one white?

The wiring is the same. White with white and black of house wiring to black or to both the black and blue of the ceiling fan. The problem is you need the ceiling fan bracket to be very secure to the ceiling. Usually you would screw right into the joist. Be careful with the pipe. If it is not capped it's probably just a fixture nipple. If it is capped it could be an old gas line that was used for a gas light.


Can a ceiling fan be installed without the blue and green wires only the black and white ones?

Assuming the ceiling fan also has lights then that is what the second lead is for. You can tie the black & blue together and attach them to black lead in the lighting box. The light and fan will come on together when you flip the light switch and you have to use the pull chain on it for control. ALWAYS connect the green ground wire to the house wiring ground. This is a SERIOUS safety and fire hazard issue if you do not.
