Light fixture has white, black, and green my old fixture only has black and white how should i hook it up?

my old fixture has only black and white nothing else. there are no ground wires anywhere near there in the attic. how should i hook the new fixture up? i tried white and black and i got nothing.|||Green is the ground wire and apparently you have an ungrounded system. If the box that the feed wires come in to is metal, then attach the green wire from the fixture to the metal box with a screw. If it is plastic, then just cap the green wire and tuck it into the box. Then the blacks go together and the whites go together and you should be back to normal. Just know that you DO have an ungrounded system and at some point you should have an electrician look at it and make suggestions. In the interim you will be fine. There are still many many ungrounded systems out there that operate just fine, but the protection the ground wire gives you IS missing. You can google for more information about ungrounded systems for general information.





Al|||Your new fixture's green wire is a ground wire. It needs to be screwed to the inside of the electrical box to act as a ground if no ground wires are in the conduit.





Now, the fixture should still work with just the white to white and black to black. If it doesn't, test whether you have power to the circuit.|||Hook the white to one wire and the black to the other then attach the green to ground.|||old wire = new wire


black - black


white - white


green wire is ground if old had no ground attach new one to junction box for ground.
