How do you connect two wires on light fixture to a 3 wire ceiling red black white?

Answer 1

=== === A Red wire can be the first "Hot Leg" of a 240 volt supply. It could also be one of a pair of hot wires connecting two switches controlling one or more 120V lighting fixtures.

A Black wire can be the second "Hot Leg" of a 240 volt supply or the "Hot" wire of a 120 Volt supply. It could also be one of a pair of hot wires connecting two switches controlling one or more 120V lighting fixtures.

A White wire is normally the "Neutral" wire. It is common to both hot legs on a 240 Volt supply.

A Green wire (or bare wire with no insulation) is normally the local "Ground "wire. === === === === <><><> If this is a standard 120V light fixture controlled by two light switches, for more information, including a wiring diagram, see the answer to the Related question shown below. <><><> If, and ONLY if, there is an on/off switch for a 120 Voltlighting fixture installed onto a wall box containing wires having those colors, it is possible that the Red and Black wires in this situation are:

a) the "hot" feed wire coming from the mains breaker panel to the switch and

b) the "switched hot" wire going to the lighting fixture.

BE VERY CAREFUL: YOU MUST BE SURE YOU UNDERSTAND

HOW TO DO ANY OF WHAT FOLLOWS SAFELY BEFORE YOU TRY TO TEST ANYTHING WHICH MAY BE A HOT OR LIVE WIRE Only someone who knows how to use a test lamp or voltmeter safely will be able to confirm if the Red wire in the wall box is a) and the Black wire is b), or if they are actually wired the other way round, meaning the Black wire in the wall box is a) and the Red wire is b). <><><>

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

Answer 2

You call an electrician LMAO! Assuming all white wires are connected seperately from the red and black wires and that the other in the box are 110V....Connect your ground to ground, white to white and your black to either the red or black unless they are all tied together in which it wouldn't matter.

Answer 3

In theory, such an installation should be done by an electrician who knows what he (or she) is doing, not by you, however, if you insist on doing it yourself, just attach wires to the wires of the same color; also remember that while you are working on the wiring, you must turn the power off in order to avoid electrocuting yourself. You strip off about half an inch of insulation at the tip of the wires, twist them together, and then screw a little plastic cap, technically known as a marette, over the twisted wire; failing that, you can substitute black electrical tape to cover the exposed wire. Any uninsulated wire is a potential source of a short circuit which will at best blow a fuse and at worst burn down your house, so this is something to be careful about.

Answer 4

Answer for USA, Canada and countries running a 60 Hz supply service.

The information supplied in your question is not sufficient for a straight answer, but I will try. I have made the assumption that the wires described in your question are what you see in the lighting box, not the fixture. I have made the assumption that your fixture has only one black or hot wire and only one white or neutral wire.

First, one set of black and white wires (that is one black and one white wire) is probably a hot feed from the panel, possibly from another room, but likely the hot feed into the room you are lighting. Determine that set first.

Second, where do the other black and white wires go? Any that go to receptacles or to another room should be connected directly to the hot and white wires determined in my first step.

Third, any remaining wires should go to a switch, or more than one switch. For the purpose of this answer I will assume there is only one switch. I would expect these wires to be one set of black, white, and red wires. If this is the case, forget the white wire. Cap it off or tape the end and ignore it. I never cut unused wires. You may never know when you might need it.

Connect the black wire to the other black wires. Connect the red wire to the black or hot wire from the fixture. Connect the white or neutral wire from the fixture to the other white wires. At the switch, cap off or tape the end of the white wire and ignore it. Connect the black wire and red wire to the switch on different screws. There should only be 2 screws and electrically it doesn't matter which wire goes on which screw.

You are done. This answer has not addressed any ground wires that might exist, and there should be. This answer assumes what I would expect the first time through trying to figure out which wire goes where. If at any point my answer does not fit what you are seeing then it gets more complicated and you need more information.

Answer 5

It is strange that a ground is not currently installed. For safety a ground is required. However, the good news is that a ceiling fixture provides little chance of a shock hazard except when servicing the fixture. However, the missing ground should be a warning that other things may be wrong with your wiring and you should consider having an Electrician check your overall wiring for issues. It is likely that someone has done some rewiring in your house and they may have screwed up other things.

Depending on the age of the home there may not be a ground wire in the box. you can tell the old wires because the have a tarred paper jacket instead of a thermoplastic one. if this is the case just ignore the ground wire it is not required to make the fan function. and unless you are changing the electrical circuit you do not need to bring it up to current code.

Answer 6

If it is a normal installation connect the two white wires with a pigtail, two blacks with a pigtail and ground wire connected to the back of the box grounding screw. The two pigtails connect to the light and cap the extra wire with a wire nut.

Answer 7

ok, you know the battery pick the two that's connected to the batterys if they are all connected just pick any of them
