How to Install Electrical Wiring for a Bathroom Remodel Project
Electrical Wiring for a Bathroom Remodel Project: Can I install an exhaust fan on a circuit that is GFCI protected? Installing Electric Wiring for GFCI protection, GFCI Requirements for a Exhaust Fan that is Over a Bathtub or Shower.
Bathroom Electrical Wiring and GFCI Protection
Electrical Question: Can I install an exhaust fan on a circuit that is GFCI protected?
- My plan was to put the outlets on 20a breaker (first outlet to be GFCI and run second in series).
- The main light and wall sconces to be on 15a breaker (with other lights from other rooms).
- My Question is for the exhaust fan.
- Does the Exhaust Fan need to be protected by GFCI because it is over tub or shower.
- Can I run the exhaust fan from 20a breaker since only 2 outlets and already GFCI protected.
- I might put the fan light on 15amp circuit, but I do not know what might be better.
Thanks in advance,

Electrical Wiring for a Bathroom Remodel Project
Preparing for a Bathroom Remodel Project
Application: Bathroom Electrical Wiring.
Skill Level: Intermediate to Advanced – Best Installed by a Licensed Electrician.
Tools Required: Electricians Pouch of Hand Tools for Rough-In Wiring, Electric Drill and Auger Bits and Extension Cord.
Estimated Time: Depends on the extent of the bathroom remodel project, the type of construction and available access to the project area.
Precaution: Any existing wiring in the immediate area that may interfere with the installation of new construction materials should be identified, turned OFF and Tagged.
Notice: Modifying existing wiring or installing additional bathroom electrical wiring should be done according to local and national electrical codes with a permit and be inspected.
GFCI Requirements for a Exhaust Fan that is Over a Tub or Shower
- If the dedicated 20 amp circuit supplies only one bathroom then the bathroom exhaust fan may be added to this GFCI protected circuit.
- It is always good to have the bathroom outlet on a dedicated 20 amp circuit with GFCI protection.
- If a separate 15 amp circuit is installed for the bathroom light and exhaust fan and the exhaust fan is over the tub or shower then GFCI protection will still be required, which in this case a 15 amp faceless GFCI may be installed and the circuit can be wired so the vanity light is not on the GFCI but the exhaust fan is.
