My house is wired mostly with EMT conduits and metal boxes. Therefore I typically do not have ground conductors for those runs.

In a half bath I have all I got is a 1 gang metal switch box behind very thick porcelain wall tiles. Ideally if I enlarge that junction box to a 2 gang, I would have room for a gfci receptacle and a duplex switch - one for exhaust fan one for wall scone. As it is now I have a 1G box, so all I have is a single device at the wall, a switch and receptacle combo. The switch controls both the light and fan, the receptacle is not gfci receptacle. I couldn't find a switch/receptacle combo that is GFCI, do they make one?

So I am going to put in a GFCI breaker at the panel for this half bath.

The breaker instructions call for an isolated ground wire. I assume even though I am on EMT, I still need to pull a green conductor for this right?
