How do I connect 2 hot and 1 common to only one positive wire?

Question

The problem is that I am trying to install a ceiling fan into an old building. The fan has 4 wires that need to be hooked up. 2 hot, 1 common, and 1 ground. The section that I am trying to install this fan in only has 2 wires, a positive and a negative. The big question here is how do I wire this so the ceiling fan and light work

Answer 1

Hook the black wire from the fan(hot) to hot.Hook the wire for the lite to the same hot.If its an old building hook the ground to the metal box and just hook the white wire(common) to the other common.The fan will work with either the pull chain or lite switch.Or it will work lite and fan with the pull chains..

Answer 2

you are saying that you have one hot wire coming in from the house and one common if i read it right.

connect both black wires from fan to this one hot wire from you house. connect the white wires together also.

The two black wires in your fan are, one to fan, and one to lights, they can operate off of the one circuit from you house power supply.

Answer 3

You make what is called a pigtail, using a wire nut to wire both hot (likely black & red) from the fan to hot (likely black) in the building.  Wire nut the commons together and connect the ground to a metal box, if one is installed.

Assuming the two wires are coming from a switch, if you want either the lights or fan to have power, then you will have to have the switch on, and use the pull chains to select which is off and which is on.

First thing, check to be sure the old box will support the weight of the fan; a standard 8-B box (especially an old one) is not likely to be "Fan Rated". The last thing you need is to have the fan come down onto your table, guests, or your head.

Second, in AC wiring, stop thinking in terms of positive & negative, they don't exist. What you have are Ungrounded conductors ("hot"), grounded conductors ("neutrals"), Equipment Grounding Conductors ("grounds", and switch legs. In single phase residential wiring, that's all there is, period. ("Common" is a common term for the neutral, but no one seems to be able to tell me what it's common to when I ask them. Learn the correct, Code terms for wiring & components, and then inspectors, installers, sales reps, UL Engineers, Contractors, and the Code Making Panels will all be speaking the same language.) In your situation, you have no "hot" conductors, unless you have no wall switch to control the old lighting fixture.

Assuming the box will support the weight of the fan (and I"M NOT), and that you have a pull-string switch for one or both parts of the fan/light combo; your next step is to twist the two switch leg conductors from the fan assembly together. Now, if they are aluminum, coat them with an anti-oxidation compound (actually, it's best to do this before and after twisting them together) and, using the correct size wire-nut, splice on about an 8" pigtail of the correctly sized wire; splice this to the switch leg in the ceiling box. Do the same with the neutral, adding a pigtail if you think you'll need the slack to ease the installation. Now, add a grounding pigtail assembly (you can purchase them pre-assembled at most hardware stores and home centers) to the ceiling box (be sure the assembly is green insulated, and that you secure it to the box with a listed and identified means - this means, use a green 10-32 ground s***w, or a green, listed grounding clip. Now, splice both the grounding conductor from the fan, and the existing equipment grounding conductor from the box to this pigtail.

Finish installing the fan assembly per the manufacturer's instructions, and it should work just fine. You'll have to use the pull-strings to change the speed and direction of the fan; use the wall switch to control the light.

My last suggestion; hire a qualified, Licensed Contractor to do the job. He (or she) will be sure the box will support the fan, properly install a new box, if required, and be sure that everything is functioning properly, as well.

Answer 5

the two "hot" wires from the fan are: 1. the light, (usually blue)and 2. the fan, (black)

twist them together and attach to the hot wire from the ceiling.

twist all the neutrals  together, and the grounds tie together (be sure to ground the box,also-a separate wire from the box to the ground splice). the two "hots" (coming from the fan motor) are in case you wanted to operate the light and/or fan from separate wall switches. hopefully, the fan and light have separate pull chains to operate independently. finish mechanically installing the fan motor, blades, and light kit, and VOILA! u r done! nice job!

since you have to ask you are not qualified to do the job. Get an electrician. Otherwise your insurance is void , nill, nothing
