What do you do with the yellow wire?
Yellow wires are used as switch legs to ceiling fans, structural lights, and outlets paired with light switches, while blue wires are usually used as travelers for three-or-four-way switches.
What is the LOOP terminal on a light switch?
The loop terminal is used purely for a termination of a non/switched cable. Ie not active. Some light fittings will have a loop terminal that you would put the active in. Some sparkys prefer to solder wires together in walls, as it offers a better connection (reliable) than a screwed connection.
How can you tell if a switch is a live wire?
With a live circuit, you can identify the ‘switched’ live conductor at the light fitting. Switching on the switch will make one of your blacks become live. With a digital multi-meter set this to AC volts. When the switch is closed you will see 230 V between neutral and the switched live black.
What happens if you don’t earth a light?
An earth connection is designed to take away the danger of electrocution from a fault in an incredibly fast time. Most normal light fittings have an earth terminal on them & if you don’t have an earth connection in your electrics then the electrician cant put the light up.
What happens if earth wire is not connected?
Without the earth wire, if a fault occurs and the live wire becomes loose, there is a danger that it will touch the case. The next person who uses the appliance could get electrocuted . The earth wire is therefore connected to the case and is attached to a metal plate or water pipe underground.
What do I do with earth wire if not needed?
If the earth is missing for the DIY enthusiast, you must not fit the light fitting that can conduct electricity. You should change to a non-conductive material like plastic or porcelain. An electrician may want to pull through a twin and earth cable to make the safely earthed connections.
Why do some ceiling lights not have an earth wire?
Older properties that were built before 1970 were not required to have an earth cable present. What this means is that lights that are not double insulated, used in a property without an earth wire may in turn use the person who is operating the switch as the earth and you could get a nasty shock!
Do ceiling lights need to be grounded?
Grounding and Your Light Fixtures
Strictly speaking, grounding your light fixtures isn’t necessary in all cases. However, it’s a good idea as it makes your light fixture safer and reduces the risk of injury. Metal light fixture boxes should always be grounded where you install the fixture.
Where does the earth wire go on a light switch?
Safety first – Earthing light switches
The commonest light switch combination is a metal mounting box and plastic faceplate. In this case, the earth core or cores must be connected to the earthing terminal of the mounting box. If you have a metal faceplate, the main earth core runs to the faceplate first.
What happens if you don’t ground a light switch?
In many cases, especially in older houses with metal boxes, the metal box may be grounded even if you don’t have the wire. When you screw the light switch in, it will make contact with the box, and as long as the box is grounded, it will pick up ground that way. If the box isn’t grounded, the switch will still work.
What happens if a light switch doesn’t have a neutral wire?
The neutral wire allows the completion of the circuit and the switch to have power even when it’s turned to the off position when you want the lights off. Without this neutral wire in place, the circuit is broken any time the switch is now in the off position. It remains has power when the switch is in the On Mode.
