What is the bare copper wire in a light fixture?
It is a frame ground. It’s bonded to the metal of the fixture so that if a bare live wire touches the metal it trips the breaker. If it wasn’t there and a live wire was touching, nothing would happen; until you went to change or clean the fixture. Then you become the source to ground and will get a zap.
What do I do with the bare copper wire?

What are the three wires in a light fixture?
A standard box for a light fixture will have three wires, a white (neutral), black (current), and copper (ground.)
What color wire goes with copper?
Electrical wires are wrapped in colored insulating casings to indicate each wire’s purpose. Green, green with yellow stripe, or bare copper are ground wires. Black wires are hot wires that run to the electrical outlet from the switch.
What is the purpose of the neutral wire?
More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. This gives currents circulation through your electrical system, which allows electricity to be fully utilized. Additionally, this prevents faulty or excess currents from residing in your outlet.
Is bare copper pure copper?
What is Bare Copper Used For? Bare copper wire refers to a single strand of copper wire that does not have an extra coating. The wire consists of 99.99 percent pure copper and can be used as a single wire in ground conductors, hook-up wiring, and jumper cables.
Why does my ceiling light have 3 cables?
Your 3 reds in a connector are the permament lives. The three blacks are the neutrals. The single black will be your switch wire and should be tagged with a red/brown tape and the other red will be a switched live connection between the two lights. All the earths should be connected in a block.
Why does my ceiling light have 3 white wires?
The black wire is the hot wire, the white wires are neutral and ground is ground. You need to connect the black wire of your light fixture to the black ceiling wire, the white wire fixture to the 3 white wires, and the ground wire to the ground wire.

Does a plastic light fixture 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.
Do you have to connect the ground wire on a light fixture?
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.
Does a pendant light need to be earthed?
Any light, lamp, bulb holder or fitting with a conductive or metal exterior surface must always be earthed to ensure against risk of electrocution or serious injury.
What happens if you do not connect the ground wire?
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.
What is the purpose of a ground wire on a light fixture?
The purpose of a ground wire is to give excess electrical charges a safe place to go. The solid mass of earth below our feet has a negative electrical charge, which means positive electrical charges are naturally attracted to it.
Do you need to cap ground wire?
Wire nuts that are too small may initially feel like they are on the wire, but they, too, may fall off. Bare copper ground wires do not need to be capped. Similarly, BX cable’s metal armor sheathing, which conducts to ground without the need for an additional ground wire, may be left alone.
