Do plastic light fixtures need to be grounded?
Grounding and Your Light Fixtures
Plastic light boxes won’t conduct electricity so they don’t have to be grounded, although most will come with a grounding screw.
Does LED retrofit need ground wire?
Now, any fixture that uses LEDs, or a bulb that uses LEDs to replace an incandescent bulb, must be grounded, similarly to the incandescent-bulb-using fixture. If not grounded, these fixtures use 110/120 volts AC power and might cause injury.
Is it OK to install a light fixture without a ground wire?
Yes, if you have a metal light fixture your fixture needs to be grounded. The ground wire exits your junction box, but it is not attached to your junction box.
What to do if there is no ground wire on light fixture?
You can either wrap the ground wire in the electrical box with tape and let it float in the electrical box, or you can attach the ground wire in the electrical box to the light fixture, or appliance, itself.
How do you ground a plastic wire?
Plastic boxes cannot be grounded in the same way. But it’s still necessary to bring the equipment-grounding conductor into the enclosure to ground devices such as switches and receptacles. Connect the bare or green wire directly to the green screw on the device.

Why do some light fittings have no earth?
If any of our lamps, lights or bulb holders do not have an earth connection it will be because the outer surface is predominately made from a non conductive material such as glass, plastic, ceramic or bakelite etc, therefor it is not necessary to earth the unit.
Are ground wires necessary?
The ground wire is not strictly necessary for the operation of a device, but it is still an important feature. This wire is designed to provide a path for electrical current to travel if the normal paths aren’t available. This could be because the other paths are damaged, or there is too much electricity for them.
Why do leds not need ground?
No – LED lights do not need or justify different grounding or protection – they carry the same electricity and have the same risks. Actually, more (along with CFL’s) because filament bulbs usually fail by shorting of the filament, which results in an open circuit.
How do you ground a light fixture?
Locate the ground wire coming from your home’s electrical box where the light fixture is to be installed. The ground wire will be either green or bare copper wire. If the wire is covered with green insulation you will need to strip 1/2 inch of the green insulation off of the tip of the wire.

What do you do with the earth wire in a plastic light switch?
Earthing conductors will protect you against electric shock when a fault occur they trip. This is only necessary to be connected to metal parts which are conductive. In case of plastic boxes or accessories they are not necessary and obviously there is no place to be connected.
What happens if ground wire is not connected?
Is the ground wire necessary? The appliance will operate normally without the ground wire because it is not a part of the conducting path which supplies electricity to the appliance. In fact, if the ground wire is broken or removed, you will normally not be able to tell the difference.
