in an ac series circuit there are 30 bulbs are connected in

I've descovered that when the earth wire in a domestic
electrical installation is not connected back to the board
(ground) a voltage of between 9-24v is is found to be
present in the earth wire.
When connected at the board there is no voltage - is this
normal and why does it happen?
