Understanding Light Fixture Electrical Wiring
The Basics of Light Fixture Electrical Wiring: Electrical testers enable you to identify electrical circuits and help prevent the possibility of accidental electrical shock.
Basics of Light Fixture Electrical Wiring
Electrical Question I’m installing a light fixture.
- There are three wires–black, white, and red.
- Wire testing shows black is the ground.
- When I attach my light fixture’s ground to black and switch power back on, I have no power to anything.
- To circumvent this, I attached the light fixture’s ground wire to the screw for ground wires on the crossbar.
- I then attached the hot wires and the light works fine.
I Have Two Electrical Questions:
- Why do I lose power when I attach the ground wire?
- Is it safe for me to leave everything hooked up the way it is?

Thanks for your electrical wiring question Eric.
The Basics of Light Fixture Electrical Wiring
- Eric, the readings that you are getting may be caused by a number of factors,
- including not fully understanding or considering all the other components that are connected to the circuit,
- switch positions,
- ground connections
- or neutral connections.
