Wiring a light fixture in bathroom attached to a switch and GFCI


I am replacing all the components in my bathroom during a remodel. I have a box that has a light switch and a GFCI, the switch controls the vanity light. When i removed the old fixture I neglected to note how everything was hooked up.

Everything seems to be hooked up properly, the switch controls the fixture with no problems, but the GFCI won't reset it stays tripped.

Any ideas?

The box for the switch and GFCI seemed straight forward, two sets of 3 wires, 1 black, 1 white and 1 ground. One set for the switch and one set for the GFCI. The box for the light fixture has 2 black and 2 white wires. One black wire is loose, the other is attached to a black wire that goes into the wall and this connection is wrapped in uninsulated copper wire.

I also have 2 white wires. So, I attached the black wire to the black wire on the fixture, and both white wires to the white wire on the fixture and the ground wire from the fixture to the green screw on the mounting...

–Check local regulations for restrictions and permit requirements before beginning electrical work–

This page contains wiring diagrams for ground fault circuit interrupter (gfci) receptacles. Included are diagrams for multiple gfci's, a protected standard duplex receptacle, and a protected light fixture. Wiring for a switch and gfci receptacle in the same box is also shown to protect the switch and light or to protect other receptacles in the circuit. To wire a gfci circuit breaker see this link and wire a gfci switch combo at this link.

GFCI Receptacle and Light Switch

This diagram illustrates wiring a GFCI receptacle and light switch in the same outlet box, a common arrangement in a bathroom with limited space. The hot source is spliced to the LINE terminal on the receptacle and to the bottom terminal on the light switch. The neutral and ground wires are spliced together and run to each device in the circuit.

Fix a Bathroom Light Fixture

Electrical Question:How can I fix a bathroom light and fan that stopped working?

Bathroom Light Fixture Problem #1

I have a 1975 townhouse, and as a single mom I find myself having to learn and do a lot of things by myself. My daughter’s bathroom has both a fan and light switch (single-pole wall switch). The fan was not working so I thought I would replace the switch for the fan. I had forgot to turn off the power at the electrical panel and there was just a little spark–I know, Be Careful. Well now the fan works, but the light does not. The two slot receptacle (15 amps, 120 volts) works, but it also affected the light in my bathroom and the GFCI receptacle. I have aluminum wiring and if there is a overload it trips, but I know it is not the fuse because everything else is working. I have been researching I think it has to do with the GFCI am I on the right track?

Providing electric circuits to bathrooms are like kitchens but unlike bedrooms. Bathrooms are damp so wiring must be GFCI-protected and exhaust fans must be provided.

Bathrooms are unique in the home when it comes to electrical service. By nature, bathrooms are damp environments and water and electricity make poor bedfellows. The previous article examined wiring a kitchen; the next one discusses powering a laundry room or workshop. This one discusses how to wire a bathroom.

Review: Basic 120V and 240V wiring

120Volt circuit requires 2 wires to complete circuit
120Volt requires Hot and Neutral
When installing a switch, the Hot wire is cut, and switch installed.
Switches always turn the Hot wire on-off.

Neutral wires are never connected to switch
Only the hot wire is turned on-off. The neutral is always continuous between Load and breaker box

240Volt circuit also requires 2 wires to complete circuit
240Volt requires Hot1 and Hot2.
No Neutral wire is involved in 240Volt circuit
Read more
240Volt circuit can be turned on-off by cutting power to either Hot1 or Hot2
Double-pole Switches can turn both Hot wires on-off.

Three Parts:Removing Old SwitchesInstalling a Double SwitchTroubleshootingCommunity Q&A

A double-switch allows you to operate two lights or appliances from the same location. Double switches, sometimes called "double pole," allow you to separately control the power being sent to multiple places from the same switch. For example, you might want to turn on a bathroom light separately from the ceiling fan. To wire a double switch, you'll need to cut the power, remove the old switch, then feed and connect the wires into the double switch fixture. Though it is not difficult to wire a double switch, careful attention to safety is crucial to prevent injury.

Note: This article only describes installing the switch itself, not rewiring two conjoined feeds that need to be separated. If you are trying to separate two lights that use the same wiring, as opposed to two already separate sources, you will likely need a trained...

It can be downright frustrating to do electrical work.

But I found a light switch that’s easy to install and looks awesome.

I almost had my daughter wire this light switch but then imagined what my wife would say!!

If your switches look old and grimy you may need to replace them.

Especially if you want a modern looking home.

Today I’m going to show you how easy it is to install a new switch.

And I’ve got a give away that could literally save your life

Every week I walk through Lowe’s or Home Depot looking for the newest supplies.


So I can share what I find with you.

This past Saturday I spotted something really cool: Adorne light switches.

Maybe I’ve been living under a rock but I’ve never seen these before.

After investigating the Adorne switches and outlets I decided to buy one.

I did this for two reasons

To see how they differ from traditional switches and To share a few...

Wiring Home > Electrical > Electrical Outlets > Ground Fault Electrical Outlet This section covers do it yourself wiring of an GFCI electrical outlet. A GFCI outlet is different from conventional outlets. In the event of a ground fault, a GFCI will trip and quickly stop the flow of electricity to prevent serious injury.

The National Electrical Code requires that outlets in wet locations be ground fault protected. You will need to use a GFCI outlet in the following locations; The Bathroom, All Kitchen Counter top outlets, All Garages and sheds, Basements and Outside outlets. In addition outlets that are outside must be in a weather proof enclosure.

Definition of a ground fault:
Instead of following its normal safe path, electricity passes through a person's body to reach the ground. For example, a defective appliance can cause a ground fault.

A GFCI outlet does NOT protect against circuit overloads, short circuits, or shocks. For example, you can still...

There will be three wires: one black, one white, and a separate ground wire that may be bare copper or is sometimes wrapped in green. Inspect the quality of the wires. If any of the wires seem weakened, trim and re-strip the end of the wire to meet your needs.

Identify the three different colored wires, and attach the new light switch to the wires in the same way they had been attached to the old switch. If your wires are solid copper, create a loop in the end of the wire with the pliers and guide it around the screw on the side of the switch. Tighten the screw, ensuring that the wire is securely held beneath the screw and is not splaying to the perimeter of the screw. If your wall wire is composed of a group of smaller wires, use the pliers to gently twist the ends of the wires together to make them “whole,” and then follow the same...

Last week I described how an outlet should be wired for switch control when the voltage enters the circuit at the outlet. This setup is how our master bedroom was wired before I installed an overhead ceiling fan. As promised, I detail below how to modify this wiring setup with minimal effort so that the switch can instead control an overhead fixture. Later this week, I’ll post some before and after pics from our ceiling fan installation. Before we get started, let’s briefly review last week’s diagram:

Review of Switched Outlet Wiring (Power Enters at the Outlet)

In this diagram, voltage enters the circuit at location (A) in a standard 2-wire (+ground) Romex. The white neutral wire from this Romex is connected directly to the silver terminals on the receptacle (E), and the black hot wire is connected to the white wire running to the switch (B). The white and black wires from this Romex are connected to the switch (C). The black wire at the switch is now...

Dimmers & fans will absolutely not trip a GFCI inadvertently. I do recommend using one GFCI recept, not more on the same circuit. The other recepts can be regular and attached to the load side of the GFCI one and will inherit the protection. All my bathrooms lighting is on dimmers, the fan is on a timer, and all are on the load side of my GFCI (protected) and have never tripped.

There's basically 2 methods for wiring a bathroom by code...

Here's your choices

1.) All the recepts of bathrooms can share the same 20A GFCI protected circuit. Lights & other stuff go on another circuit. Since all the recepts of the bathrooms share the same circuit the breaker will trip if 2 people use a hair dryer at the same time in different bathrooms but since lighting is on a different circuit they won't be left in the dark. I find this useful when there's a small master bathroom with a regular bathroom on other side of the wall. Just one 20A circuit to a GFCI recept and the...

Thanks for all your help and input Petey_Racer. It is appreciated.

First, the reason why I'm doing it myself, then a question.

So far I have had 3 electrician friends come to my home and discuss the electrical, and have 3 different answers to my questions. Seems there is a big gap between a Pro and someone that knows how to do it correctly. This is common for all aspects of pool construction.

Some fun examples from the electrical "Pro's" that came by.
Prior to this thread, I explained to one that I planned on using a 220v GFCI breaker for the pump motor, and the expert that has been doing home wiring for 10 years said there is no such thing as a 220v GFCI breaker, "they only come in 110v breakers". A week later I saw him again, and he said "Oops", I was correct. (I have seen similar posts in forums from Pro's that also didn't know those existed). Same guy also wanted $1000 to change out service panel. I later did it myself for $160, then had the "Pro's"...
