Home electrical wiring for bathrooms - Plan Design by: Heidi Agler
Code requirements and energy efficient specifications now incorporate the following methods into a new or remodeled bathroom project.
Bathroom Electrical Code Requirements
Home electrical wiring for bathrooms lighting must be either: on dimmer switches, provide a "manual-on
occupancy sensor", or be all fluorescent lighting.
Bathroom
receptacles are to be supplied by at least one 20 amp branch circuit.
This circuit shall have no other outlets except bathroom receptacles. Bathroom outlets must be protected by a GFCI device. More about GFCI devices.
Hydro
massage bathtubs and their associated electrical components must have
GFCI - ground fault circuit interrupter.
All electric motors shall be readily accessible for servicing purposes.

Questions about Bathroom Wiring
Question from Joe, a Homeowner in Mariposa, California: My bathroom light and fan do not work when switched on, what could be the problem?
The age of our home is 30 years, and there is a problem in the guest bathroom where the light and fan do not work when switched on. Each has its own separate switch. There is one GFCI plug installed in the bathroom. The GFCI has two pair of wires; one pair (hot) is connected to the LINE connectors on the GFCI connector. The second set of wires are connected to the LOAD section. The GFCI appears to be okay.
Also, the adjoining master bedroom has two outlets that do not have power.
The circuit breakers in the electrical panel seems to be working fine, there’s 115vac on the output side. All wires on the output side leading into the house are tight.
Thanks for any suggestions you can offer in finding the problem.
Dave’s Answer: Troubleshooting a Bathroom Electric Circuit Problem
Joe, I suspect that the affected bathroom circuit has lost connection with either the neutral or the power wire. The circuit wiring should be checked starting at the last device that is working. Often we find a faulty wire connection to a receptacle outlet, or a burnt wire splice in a wire connection. Removing the affected circuit components and replacing them with components of the same specifications will typically solve the problem and restore the circuit power.
I have a ceiling light in my bathroom with two 3way switches. I want to add some sort of a light Or lighted switch that would be on when the bathroom light is on, how can I wire this?
How to Wire Your Bathroom so the Lights and Fan are on Separate Switches – The key factor is to understand where the power source enters the circuit – The power source will either enter at the switch box or up at the light fixture or the exhaust fan.
Replacing GFI Outlet Leads to Sparks: I was replacing a GFCI receptacle,I had accidentally pushed the travelers together with a flat head screwdriver, so the wires sparked, and now my whole bathroom and bedroom, has no power whats so ever
When switching on bathroom light my fuse box trips. Have checked all the wiring to light switch and light and they seem to be connected…

NO POWER TO OUTLETS AND LIGHT SWITCH IN BATH ROOM
Robert asks::
The other night we hooked up a new sauna. While running the sauna one of the kids started the washer and it tripped the circuit breaker. I reset circuit breaker but now I have no power to the lights fan in the downstairs living room. On the east wall of living room two outlets have no power and the downstairs bathroom light switch has no power. I removed and replace circuit breaker and removed and replace both outlets in the living room. I also replaced the light switch in the bathroom, but still no power? All other outlets work in the downstairs living room.
I'm Puzzled
Dave's reply:
Robert, I can't help to be curious about the addition of the sauna circuit and how it was installed. When something like this occurs, I always work the problem backwards starting with the most recent work that has been done and begin an inspection of what exactly was done and by who, and of course was it done according to code and inspected, with the GFCI for the sauna being tested. Once the sauna circuit installation has been verified to be ok, then a process of testing and inspections would need to take place starting at the electrical panel by a qualified electrician in order to find out exactly what the cause is.

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.
David in New Jersey asks: In a new full bath is a 20amp circuit enough for the GFCI Outlet, the Exhaust fan, Vanity Light and Two Down Lights?
The lighting will all be LED so not much of a load there.
Dave’s Reply:
Single bathroom Circuit
Yes. The typical circuit for a single bathroom is 20amps, and may be used for the devices you plan to install.
