Do I have ground wires coming to my electric panel?
My house was built in 1987. Yesterday I wanted to install timer switch in the bathroom, but it looks like there is no green ground wire that is required by the switch. I've check couple regular 3 prong outlets in the house and it looks like all of them are not grounded.
The house is wired using steel non-flexible conduit. I've also attached the photo of my electrical panel. I do not see ground wires other than the main one. Also there are couple dead-end wires on the bottom of the panel. Is it normal?
I would appreciate your advice on this. Do I have ground wire? Can I use conduit to ground switches and power outlets? Should I have electrician add ground wire? I have about 60 switches and power outlets. What the cost of running a green wire will be in Illinois?
