Color Variations With Conduit Wiring Method
[ad#block] Electrical Repairs Question: My home was built in 1967. It has single strand wiring through conduit. It appears most of the application is blue for hot and white for neutral. The project is installing a new light fixture in my bathroom, following a remodel. From the wall switch, the top terminal has an yellow wire, the bottom a yellow wire up to the junction box for the fixture (which is on wall, not ceiling). Also at the fixture junction box comes a white wire. The basic question is, what are my connections?
Thanks for your help! Tim

Thanks for your electrical question Tim.
Conduit and Electrical Wiring
Tim, the white neutral remains the same, however the power source is the blue wire and switched power to the light fixture will be the yellow wire.

The Safest Way to Test Electrical Devices and Identify Electric Wires!
The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!
The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..
The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
