It would depend on where it bridged itself (if it does). It might
already have done that, in which case the measured voltage is even more
worrying!

doesn't worry me in the least because I expected it.

I don't think you can be sure exactly where the voltage drop is coming
from though can (even) you?

No but againn I donlt care.
We have those 3 pin sockets in the lab that supply power that are just like those in everyones house, hwo often to yuo worry whether the volatge at that point is 200V or 240V ?
How often to you measure it to check, before vacuuming do you check the voltage before or during vacuuming if not why not ?
