I purchased a house a few weeks ago and got the power connected about a week ago. The house has been empty and I leave all the circuit breakers off. The Meter is digital but the display doesn't seem to work. I can check online with a few days delay. I decided to check and to my surprise there's a 82 kw usage at a supposed rate of 27 kw a day. I immediately called the power company and they said that might be a deviation to ground. The outside main breaker is on.
Is this possible even when there's no power inside the house? If so how can I test where is this deviation at?
