Not necessarily, it depends how it was wired, and IT IS VERY DANGEROUS to assume that any particular wall switch was wired to kill the power to whatever it controls. (Such as a light fixture or a socket outlet.)

The only safe way to kill the power supply in your home before you do any work on anything like a light fixture, a socket outlet, a kitchen range - or anything else! - is to switch off the big "main switch" on your home's breaker panel.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.

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.


When you switch off a 3 pin power socket at the wall is it still earthed?
