I am installing a new bathroom ventilation fan and light in the bathroom where only a light was. When I cut into the ceiling to get to the joists where the housing wiil be hanging, I found knob and tube wiring. Is it safe to install the ventillation fan/light combination without changing the wiring and how do I ground the fan since the knob and tube does not have a grounding wire?

i am replacing all of my K&T. the whole main floor of the house has it. its not that big of a deal. though getting to it can be a BIG deal. anyway. the basement was all upgraded. and the K&T was used to go up from the new basement wiring.
my point is,perhaps they left the K&T in some areas and connected that to new stuff somewhere else. so he may not have to go all the way to the panel.

look at the panel and see what is connected to it.
