Can I install a combo switch and gfci in my bathroom?

A 120 volt power source must be located and installed to the desired location for the gfi outlet…

Electrical Question from Jim about Bathroom GFCI Wiring
Background: Jim, a Handyman from Baltimore, MD
Question: Hi,
I would like to install a combo switch/gfci outlet in my bathroom, but can’t seem to find a good diagram or description of how to do it. What I have currently is a switch that operates the light over the bathroom sink. In the switch box is a brown, white and bare ground wire.
Thanks,
James

Dave’s Reply:
Thanks for your electrical question Jim. If all you have in your switch box is two insulated wires that are attached to the switch then you will not be able to install a gfci outlet at this location because a neutral wire is not at this location.Â A 120 volt power source must be located and installed to the desired location for the gfi outlet.
