I am replacing an old pale fixture that has be connected to a switch box with dimmer. The house be built in around 1969 or 70. Not oodles updates to fixtures.
The existing wiring surrounded by the junction box is adjectives whit/off white. I have identified the LIVE wires that are cap together and they were connected to a smooth rope from the old fixture ( the ancient fixture had three wires. Two that be connected but could be perferated apart. One feels smoother than the other. The third cable is copper and twisted around a screw attached to the support bracket.). The second wire (rougher feel) from the feeble fixture was connected to another single chain in the fork box. There is a third group of capped wires surrounded by the junction box that wasn't connected to anything.
The unusual fixture only have (4) black and (4) white wires. The wires are in sets directly from respectively light bulb socket. There is no copper cable like the outdated fixture. I don't know how to distinguish what should be attached to what.
At the light terminate of the wires, If there are two wires with the sole purpose there, connect one cable to the all of the black wires from the fixture and connect the other chain to all of the white wires from the fixture. It doesn't event which way you connect them. The cable screwed to the metal box goes to the green flex from the fixture, if there is one. If within are more than those two wire plus the ground, you requirement to find someone who knows electricity to look at it.
As long as the switch is still working, evacuate those wires alone.
You did turn off the power first, right?
In a newer house the wires would be black (possibly red), white and green. The black (red) telecommunication is power, the white wire is colourless and the green is ground.
For a light switch, the white rope goes from the switch box directly to the fixture. The black (red) flex goes into one side of the switch afterwards out of other side of the switch and up to the fixture and allows you to turn the light on/off. The green cable is the ground circuit.
The copper wire is a ground and is really no crucial in a desk light. The black wires are the hot or power wires and the white is the neutral.
From what you are describing contained by the box the installer switched the neutral wires instead of the hot wires, which is wrong.
Assuming the power for the fluffy is in the switch box, one black (hot) line goes to one screw on the switch the second one go to the other screw on the switch. The neutrals should be capped and tap together.
In the ceiling box (there should be one there, but for put one in) all the blacks connect to the hot lead from the switch box and the whites to the neutral. Cap the wires and put a piece of video around the cap and flex so it will not come loose.
Think of it as a circle, with the switch interrupting the flow of electricity. You can put a dimmer switch rear legs in or a simple on and rotten switch, they install the same opening. Again, be sure to cover your caps and screw (where you put the wires on the switch) with black electrical video to prevent them from coming loose.
Answers: The first thing that you call for to do is figure out where on earth the power is coming from and going to
The best situation is that it would be coming from the switch and going to the light
You would enjoy 2 wires in your ceiling box a black and a white aka a hot and a indeterminate
Connections are all black to black and adjectives white to white .
That's the easy one
The other possibility is that the power is coming through the ceiling box and going to the switch box
Here's what it could look resembling :
You will have at tiniest 2 -3 wire splices as wires will turn to other places
Your fixture will be wired like this
The white will be in motion to one of those 3 wire splices
The black will walk to the black wire returning from the switch
There will be a nouns from one of those black 3 wire splices to the WHITE rope that provides power to the switch.
The white wire is supposed to hold either black paint or video on it to indicate that it's hot -but don't count on it.
