How to Wire a Bathroom Light Switch
Electrical Question #1: Where do all the wires connect to the light switch?
I’m replacing a light fixture in a bathroom.
- The bathroom also includes an exhaust fan, no light, two separate switches for light and exhaust fan. The connections from light to box are black to red wire, white to white wire, ground to green wire. There are also two cream wires coming out of box that I assume are for the fan. Do they connect to the hot wires red/black or to each other to complete the circuit?
This electrical question came from Trudy, a Homeowner from Vernon Hills, Illinois.
Electrical Question #2:
- I’m replacing a light switch in the bathroom. The switch it is next to but appears to be independent from the bathroom fan switch. It was originally rear-connected but I’m side connecting it instead. The ground appears to be a stripped loop in a wire that was looped around the top pole of the switch. What is the best way to reconnect the ground? I don’t think I can loop it with the wire on the top pole, and I’m not sure where it goes, so I just don’t want to cut it and move it to the grounding screw to connect it. My electrician dad died a couple of years ago and unfortunately I never inherited any of his skills. Any suggestions?
This electrical wiring question came from Curt in West Bend, Wisconsin.

Electrical Wiring for a Bathroom Light Switch with Wiring Diagrams
Application: Wiring a Bathroom Light and Exhaust Fan.
Skill Level: Intermediate to Advanced – Best performed by a Certified Electrician or Licensed Electrical Contractor.
Tools Required: Basic Electricians Pouch Hand Tools and Voltage Tester.
Estimated Time: Depends on personal level experience, ability to work with hand tools and electrical troubleshooting skills.
Precaution: Identify the circuit, turn it OFF and then Tag it with a Note before performing any wiring or inspections or repairs.
- Trudy, from what you have described, the cream color wires should be verified, however each function for a light or exhaust fan will require a hot, neutral and ground wire to be connected to a voltage source and through the wall switch.
- Once the power source has been verified then the connections should be clear.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!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, [amazon.com], I use for the detection of Standard 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.
