I‘m installing this mounted ceiling light and I‘ve got the metal bar part up and screwed into the ceiling, now I‘m trying to wire it. On my light fixture there are 2 white wires, 2 black wires, and a bare copper wire. In the ceiling there is a white wire (which I twisted capped with the 2 white fixture wires), a black wire (did the same as with the white), and what appears to be 3 copper wires twisted together. Those 3 copper wires in the ceiling I think are the grounding wire. but they weren‘t attached to my old fixture at all (from the 70s if that matters) and they were just capped and stuck up in the ceiling. There is a green screw as part of the mounting bar that‘s screwed into the ceiling for my new fixture and I think I am supposed to wrap the fixture‘s copper wire around it but how do I attach it to the 3 copper wires?the instructions are in crappy english and suck :(
Run a bare jumper wire from the bare wires in the connection box to the bare wire in the fixture and connect it to the green screw.
Some do and some do not (you get what you pay for) . If the cover is on and tightened, it sure would be difficult for the officer.
yeah ,it have a lock in car covers.it products your vehicle very safe.
You don't have to ground an outlet, but you should. It's like a seatbelt of a fire extinguisher. You can get away without it, but when you need it, you'll be very glad you have it. The black and white wires are hot and neutral. They form a complete circuit with the fixture. If something goes wrong and the hot somehow touches the metal fixture, if you touch the metal fixture, you could get a shock. If the fixture is connected to the ground wire and the hot wire somehow touches the metal fixture, this creates a short circuit which will immediately trip the breaker or blow the fuse, and you won't shock yourself if you touch it. To have this safety feature, you need to connect that green screw to the bare wires. You might need to get a short bit of copper wire and twist it together with the three bare copper wires. Then connect the other end of that short wire to the green screw.
Frank's first sentence is completely wrong. You are required by code to connect a receptacle and a light fixture to the grounding wires if they are available. This is very easy to do and you should do it for personal safety as well as fire protection. Wrap the bare copper from the fixture around the green screw and then put the end of it in the wire nut with the other three.
