The very first thing you do is shut off the breaker to this circuit. Now if you mean in a receptacle or switch box, the incoming cable ground wire, first connects to the box ground screw and then it is twisted with the outgoing ground wire and a wire nut is screwed on the ends of the wire to hold the wires together. In the case of a receptacle the same procedure is applied except there is a short piece of ground wire also twisted to the incoming and outgoing wires. This is called a pigtail and it goes to the green ground screw on the duplex receptacle
To connect a ground wire for a light fixture, locate the green or bare copper wire within the electrical box and the ground wire on the light fixture. Connect the two ground wires using a wire nut. If there is no ground wire on the light fixture, attach the green or bare copper wire from the electrical box to the mounting bracket or grounding screw on the fixture.
On an electrical distribution system there is no allowance for soldering by code. The approved methods are set screw lugs, hypress crimp connections and thermite welds. The reason for no soldering is the low melting point of solder and the high temperature of fault current. On a soldered connection it might work for one fault but if the heat generated melts the solder out of the connection then another fault current on the same system might not have a low enough resistance to carry the fault to trip the breaker. The ground wire is there to create a low resistance low impedance return path back to the distribution panel. A high resistance or open ground connection due to a bad solder connection is prevented by not allowing it in the first place.

I see only a red and a green wire coming out from ceiling box. What are they and how do you connect them to a ceiling light?
The red and green wires are likely the live and ground wires, respectively. To connect them to a ceiling light, connect the green wire to the ground screw on the light fixture and connect the red wire to the live wire on the fixture. Make sure to turn off the power before working on the wiring to avoid any accidents.
What do I attach the green wire from the light fixture to?
The green wire from the light fixture should be attached to the ground wire in the electrical box to provide grounding for safety purposes. This helps prevent electrical shocks and protects against electrical malfunctions.
How do you connect multiple lights to one switch starting at the light?
To connect multiple lights to one switch starting at the light, you will need to run a cable from the first light fixture to the switch. Connect the hot wire to the switch, along with a pigtail wire to connect to each light. Then connect each light fixture to the pigtail wire to create a parallel circuit. Make sure to follow proper safety precautions and consult a professional if needed.
Can you connect a wall switch and a light fixture to an existing light fixture?
Yes, you can connect a wall switch to an existing light fixture by running a new electrical wire from the switch to the fixture. This allows you to control the light fixture independently of the existing fixture. It is recommended to consult a licensed electrician to ensure proper wiring and installation for safety.
What to do with ground wire in wall when wiring metal light fixture without ground wire into plastic outlet box with ground wire Basically wall has 3 wires fixture has 2 and no place to ground to?
If your metal light fixture doesn't have a ground wire and the plastic outlet box has a ground wire, you should connect the ground wire from the box to the ground screw on the metal fixture. This helps provide grounding protection. If there is no provision for a ground wire on the fixture, consult a professional electrician for further guidance to ensure safety and compliance with electrical codes.
Where do you hook the ground wire on a porcelain light fixture on a metal box?
Connect the ground wire to the metal box.
What if the light fixture has two copper house wires?
If you mean 2 bare copper wires those are the ground wires. Tie them together and then connect the light fixture ground wire which will be green or bare copper to those ground wires.
Can you connect the ground wire from a light fixture to anthing in the metal box that does not have a ground coming from it?
I always connect the ground wire to the box. However, if there is no real ground wire running back to the panel it really does you no good. The NEC requires that you rewire the circuit with the proper conductors. Remember that the ground is for your protection. Without a proper ground, you run the risk of injury or death if the fixture wiring fails.
Is is ok if the lighting fixture ground wire is wrapped around the bottom of the chain and the ground wire from the light box is connected to the ground screw on the mounting crossbar?
If you are referring to a porcelain or plastic ceiling light fixture most do not have a place to connect the ground wire. You cannot ground these type fixtures. Just connect the ground wire to the mounting crossbar and forget about connecting it to the light itself. It is on the ceiling and will never be touched unless you change the bulb and then you will have the switch in the off position. It is perfectly safe.

The red and green wires are likely the live and ground wires, respectively. To connect them to a ceiling light, connect the green wire to the ground screw on the light fixture and connect the red wire to the live wire on the fixture. Make sure to turn off the power before working on the wiring to avoid any accidents.

Make sure to follow proper safety precautions and consult a professional if needed.
What to do with no ground in wall but ground wire in fixture?
Very often the ground wire in the fixture is ignored, or just connected to the box, if there isn't a conductor to connect to. This, however, is a code violation as any fixture with a ground wire is required to have it properly connected to an equipment grounding conductor back to the panel. This is for YOUR SAFETY. Technically you should rewire the circuit with the proper conductors. It is BAD PRACTICE to connect the ground wire to the neutral or white wire because this could create a hazard of its own.
What is a ground wire?
A ground wire is a typically uninsulated copper wire. The intent is to connect the wire to an electrical appliance or fixture to provide electricity a path to ground in the event of a short, thus preventing electrocution.
Can you connect a wall switch and a light fixture to an existing light fixture?
Yes, you can connect a wall switch to an existing light fixture by running a new electrical wire from the switch to the fixture.

How do you wire a intertek 4003485 light fixture for a 42 watt fluorescent bulb?
When wiring a Intertek 4003485 light fixture for a 42 watt fluorescent bulb, follow the manufacturer's instructions provided with the fixture. Typically, you will need to connect the black wire to the live/hot wire, the white wire to the neutral wire, and the green wire to the ground wire. It's important to switch off power before performing any electrical work for safety.
