Dimmers let you to raise and lower the light level - and may have a combined or separate on/off and dimming control, so you don't have to readjust the light level every time you turn on the light.
There's a huge range of fittings available - from functional plastic to stylish metallic finishes. You can also get versions that give you two- and multi-way switching which allow you to control lights using two or more different switches, for example in a hallway. Wall-mounted light switch fittings (known as 'plate switches') can contain one, two, three or even more individual switches (or 'gangs') that let you control a number of separate light fittings from one place. If yours does not match the system shown here, that doesn't necessarily mean they are unsafe. There is more than one method of wiring multi-way lights. The lights they control should take power from the same circuit, but if yours are incorrectly wired and take power from different circuits, there will be live cables at each switch position when one circuit is isolated. Further information is available online or from your local authority.īe cautious when opening up multi-way switches. If in any doubt, or where required by the law, consult a competent person who is registered with an electrical certification scheme. Check all finished work with a socket tester (or voltage tester for lighting circuits) before usingįor your safety, these products must be installed in accordance with local Building Regulations.These confirm whether circuits are dead and safe to work on Check the circuit is dead with a socket tester or voltage tester/meter for lighting circuits.Attach a note to the unit to advise you are working on the circuit.Or switch off the breaker and lock it if you can.Put this in your pocket to avoid accidental replacement Isolate the circuit you plan to work on by removing the circuit fuse. Remember to switch off the mains power at the consumer unit/fuse box.If the power source is an electrical panel or fuse box, the cable should be cut at least long enough to reach the furthest termination point (breaker or fuse, ground and neutral bar) without the need of splicing.Never take risks with electrical safety. Before you start any type of electrical work, you must follow these following safety precautions:.Never introduce ground wire(s) to a terminal bar with only white or gray insulated wires connected or vice versa.However, if all the existing ground wires connect to one bar and all the existing white wires connect to a different bar, maintaining separate ground and neutral connections is required. If equipped with a separate ground bar, rather than connecting to the neutral terminal bar, the ground wire can connect to the ground terminal bar.Finally, connect the black wire to the hot supply or the circuit breaker / fuse and the white to the neutral supply or neutral terminal bar in the electrical panel. The ground wire should be connected to the neutral terminal bar.
#3 SWITCH LIGHT SWITCH WIRING HOW TO#
Connect the ground wire to the circuit ground wire(s) with a wire nut or other approved connection (see How to Connect Electrical Wire). Leave 8–10 inches (20.3–25.4 cm) of wire inside both boxes (source and first switch) before cutting the cable to facilitate easy connection to the switch and power source.
#3 SWITCH LIGHT SWITCH WIRING INSTALL#
Install a 2 wire cable between the power source (outlet box, electric panel, etc) and the first switch box.
