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

DevinTo 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.
