ungrounded bath fan


I just installed a bath fan on an ungrounded circuit. Was this a dumb thing to do, and could I remedy this by hooking up a GFCI outlet on the circuitry leading to the bath fan. I had an electrician say that a GFCI outlet would not help an ungrounded circuit, but i seem to read elsewhere that it could work.

The electrician is wrong. Is he really an actual electrician? GFCI protection can be used instead of a grounding conductor to retrofit old wiring. The grounding conductor has nothing to do with the functionality of a GFCI.

Ditto to mpoulton's post. A GFCI checks for a differance in current flow between the hot and neutral, it does not require a ground to work.
