Trying to change a light switch in my house. I am Chicago within city limits.
House is pretty old...it was “gut rehabbed” in the 80s but that doesn’t really mean anything. Actual building been here since 50s/60s.
Anyway, there doesn’t appear to be any ground wire. So what do I do with the ground wire I have on the switch I’ve bought. And is this lack of ground a huge issue that I need to get resolved? I’ve lived here over a year and get occasional shock in basement (but only during winter so put this down to static given it’s the dryest part of house). I attached some pictures to show what I’m dealing with.
