I live in a 100 or so year old apartment building. They are doing some major renovation work in the basement. For the last few days I have been getting lots of electric shocks when I touch various things, from the microwave to the water faucet. The air is not particularly dry and we don't have any wind, so I don't think the weather is the problem. Is it possible that the construction caused this problem (I know that they have accidentally cut many wires along the way) and, if so, what kinds of actions could cause this problem?
TIA.
