Gene's right, in that you should test for electrical function of the wires you've got. It's not obvious how to do that, so you probably will need to study up on it, via his link or elsewhere. Or just hire an electrician -- the safest option. You can't assume that color coding of wires means anything in particular, because non-electricians may have messed with it in the past, and if it's an old house its wiring may predate color coding. That said, red is often used for switch wiring. From your description I'd guess you've got at least one switched circuit for a light fixture, and, if a ceiling fan once lived there, a separate switched or non-switched circuit to run the fan motor. But you don't give enough info for me to be more specific. I'd expect to be seeing white wires too, in which case white would (probably) be neutral, black hot, and red switched hot (i.e. hot if the associated switch is on). Sounds flaky -- call an electrician.

SOURCE: I am hooking up a

1) Look at screw color.
New device has brass screws on one side, and 1 silver screw for each switch located on other side of device.
Hot wire goes to brass screw.
Wire to fan goes to one silver screw
Wire to light goes to another silver screw.
Wire to heater goes to another silver screw.

If you do not have a wire for each individual Load, then you will have to add wiring.

2) Electricians don't guess, they test.
Separate wires for testing.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot wire.
Hot wire connects to brass-colored screw.
If any wires on old switch was connected to same Hot wire, then also connect that wire to brass-colored screws.

Hot wire is identified.
Test Hot wire to each other wire in box, except bare ground.
Tester lights up on Neutral wire. Neutral wire will NOT connect to this switching device.
Next, connect one of the remaining wires to a silver screw.
Turn power ON.
Flip switch to see what Load that wire controls.
By process of elimination, add wires to each silver screw and test each by flipping switch.
Breaker will trip if you connect Neutral to silver screw.

SOURCE: ceiling rose nt working

Look for the manufacturer's wiring on line or if the product is still available ask a merchant to permit you to copy the schematic from a similar product as yours. If they want future or continued service to you they will most likely accommodate you.
If that does not work, have a certified electrician look at it to sort out the three black and four earth wires.

Twist the current pairs together and then twist the white (neutral) to your red pair, the black (hot) to black, and green (ground) to green.

Brought LED back light the wires black,red,yellow, the old back light on my bike as two bulbs with six wires 2 x red 2 x blue 2 x black n yellow.three too each bulb when i connect my new light too bike...


Hi, firstly dont think for a miniute that the black wire on your new light is the earth, using the battery as a power source put one of the wires to earth and the other to live, as the led light will only work if the power is conected to the rite pole it is important to establish wich of the new wires is earth, you may have to swap them around to get the correct order, and then conect each of the other wires to the batt poss to check the lite works,when you are happy you have the correct order you can fit it to the bike, on the kawasaki blk and yellow is earth , although you have 6wires they are only 3wires in the loom wich double up to 6 for the 2 bulbs in the lite unit, you can leave 1 of eah colour disconected,

I have a plug outlet that's powered by a three


Red wire is the live wire, black wire is the dead wire, white wire is the earth wire.
Now its the black and the red wire we are to play with. take a two wire cable, let the wires be red and black in the new cable, connect the red and the black cables of the new cable to the corresponding red and black wires of the old cable i.e. the new cable is to be connected parallel to the old cable(the connections can be made by ripping the old cable from any point) now connect a switch to the other end of the red wire. attach the terminal of the bulb to:
1) the the other terminal of the switch
2) the other end of the black wire

Wiring/connecting wire from fan to home ceiling


Hi,

this depends on where you live UK/USA et,c or other.
It is best to search the manufacturers site, to find installation codes/colours.
i.e USA use a lot Of Black and white. UK uses Red/Black Green/yellow.
And on houses that are rewired to 17th edition electrics ( UK ) the colours have now changed on mains twin and earth household Wiring. What Used to Be Red ( Live ) Is Now Brown. Black ( Nuetral ) Is now Blue. green/yellow is earth.

*** Important Note:- you should have several reds in a ceiling junction box or light fitting, these are circuit wires. ( Live From Light to next light ) The same as with Black ( Nuetral )
There will usually be 1 switch wire/Cable. this feeds a live from the switch, to the live power up to the light. many homes use a twin core and earth, from the light switch to the fitting. this may be black ( if a black/red ) has been used. *** Do not connect a black Switch wire with the remaining neutrals***
This will blow a fuse or trip a breaker.

Your solution:- connect the black neutral To the Black neutral cables ( more Than 1 at the ceiling Rose/fitting ) if there is a green/yellow or green ( this will be earth ) You may have 2 remaining Colours Possibly red and Blue or other. The Red Should be the switched Live. ( the single cable Red/Black with red tape around It ) This will be the switched Live. The remaining cable would probably be connected to the Bunch of Reds ( Constant Live ) As ceiling fans require a constant and switched live ( if the fan has lighting )

If in any doubt, consult a qualified or competant Electrician. *****And always remove or isolate the mains supply before attempting any installation*****. After the wiring is complete replace the fuse or switch on the breaker, to test your installation.

This information, is supplied by a fully competant electrician.

Thankyou for using fixya.
