Dealing with emergency electrical projects is only a job for an Emergency Electrician in London. You may require emergency services to repair a faulty electric box, install new wiring, add recessed lights and more. Occasionally, homeowners may also need the services of an emergency electrician if they need to install a ceiling fan. Installing a ceiling fan is a skill that requires practice and experience, and ideally only a professional should be used as they have the skills to do the job right the first time.
Replacing a standard single-pole or three-way switch with a dimmer switch is no different than replacing a standard switch. Remember: Dimmer switches don’t work on most fluorescent fixtures, and low-voltage lighting requires special low-voltage dimmers.
Turn off the power to the switch at the circuit or fuse panel.
Unscrew and remove the switch plate; then use a voltage tester to make sure that the circuit is dead.
Unscrew the switch from the electrical box and pull it out with the wires still attached.
Remove the wires from the old switch.
Dimmer switches are usually connected to the house wiring by short lengths of wire coming out of the switch body rather than by screw terminals.
Use the connectors (wire nuts) supplied with the fixture to attach the black wires coming out of the dimmer switch to the coloured wires that were attached to the terminals on the old switch.
Push the new switch back into the electrical box and screw it in place.
The body of a dimmer is larger than the switch being replaced. Don’t just force it in. Often, you need to re position or better organise the wires first to make room for it.
Screw on the switch plate.
Push the control knob, if there is one, onto the shaft protruding from the switch.
Turn on the power.
