Help with gfi


Hello everyone. This is my first post on this forum and I am hoping that someone will be able to help me. I am a contractor that builds aluminum patio covers for a living. I recently built a patio that I am having trouble getting passed the building inspection and here is why. I installed a ceiling fan on the patio by removing a coach light from the wall underneath the patio and running the romex wire from the coach light to the fan in conduit. The building inspector says that I need to have the fan on a gfi. Can anyone explain how I would do that? I know almost nothing about electricity but have been wiring fans directly from outdoor coach lights for years and no inspector has cared until now. Any help would be great.

I'd like to know the code article the inspector sited to require the GFI protection.

Is it legal for a GC to do electrical work in that area?

Thank your everyone for your answers. I have a new problem with the same job. The customer took it upon himself to install a gfi outlet on the same circuit as the fans that I installed outside and he claims that every time he turns on the fans he trips the gfi. Should I tell him to put the regular outlet back on and install a gfi breaker instead?

I COMPLETELY agree on both points.

NO GFI is required.

Tell your customer to figure it out, or remove the GFI until after the job is done. How is this your problem? He stepped on your toes by doing this work while you were still on the job.

I don't mean to sound like a jerk, but if you cannot troubleshoot why a GFI is tripping you have NO place wiring ceiling fans on jobs for customers. I don't care how long you have been doing it.
Right off the bat you give the professionals here cause to question your abilities. Why did you run romex in conduit, outside, to the fan? Was it a complete conduit system, or just a sleeve? Was it NM-B cable or UF cable? What kind of box did you use at the fan? And many other questions?


I realize the reason for all this. You make more money hanging the fan yourself as opposed to having an electrician do it. Right?

The capacitance from the motor windings to the motor shell probably causes a few mA of leakage current and so trips the GFCI.
This current should show up in the ground lead from the motor.
