Where does 75 KW go in a vacant house.??


Just wondering how many kw a month a couple GFIs eat up a month?? Thats the ONLY thing on in this vacant house and the meter is racking up a solid 75kw a month,,,seems like quite a bit.

I guess somehow the furnace shows degrees on the termostate,dont know how that works,,,its a brand new furnace that has barely worked yet. How much juice does it eat, not running?? (No gas service to house)(on anyway)

No frig or range even in the kitch,or plugged in.

Is this a sign of a problem?? Seems real excessive to ME??? Very small house,old and not much else there!!

GFI's dont eat up any power unless something is plugged in and drawing power. Try checking each breaker/circuit to see where the draw is coming from but 75kw per month for a vacant would not be unrealistic. Check the utility bill.. May not be the usage but the minimum charge.

I think you mean Kw/Hr, NOT Kw. Or do you really mean 75,000 watts?

That would be equivalent to a 100 Watt bulb burning continuously. Is there a sump pump, attic ventilation fan or anything like that??

Try turning of the main switch to the premises & see if the meter is still spinning. If it stops spinning after you do this, it means that something is either switched on or you have a low insulation resistance somewhere.

An insulation resistance test can be quickly & easily done on your premises to rule this possibility out. This should be done by an electrician.

Couldn't you do this by switching the main breaker off and testing resistance between hot and neutral?

Unfortunately not.

An insulation test, which should be carried as one of the few tests of an installation BEFORE initial energisation is done, with a thing commonly called a 'Megger' or Megohm meter. This device usually places between 250 v & 1000v on the cabling. If the cabling is good, the meter would indicate infinite Ohms resistance. A minimum safe result would be 2 Megohms. Anything less than 2 Megohms & Houston, you have a problem.

Is it possible that someone is using your power without your knowledge? Like an extension cord for a construction project that has no power yet.
15,000 watts is a lot of power for an empty house, and how were you able to measure kilo watts anyway?

Actually, the OP quoted a figure of 75 kWh (kilowatt hours) over a period of about 1 month, which is not really a lot of power. E.g. if you have an appliance that draws 2.5 kW (a good example would be an electric heater) & you use it for 2 hours, you will have used 5 kWh of energy. There are 720 hours in a 30 day month so 75 kWh's is not a lot of energy for that period.

And yes, it is possible that somebody could be tapping into your power supply but this sort of thing is usually obvious.

Do you have an electric water heater "on" there? That would be my "usual suspect". Electric water heaters can use up to 14% of the power for an average home.

Could be many things such as
Garage door opener
Door bell transformer
Furnace or AC low voltage power supply
Smoke detectors?
security system
buried cable leaking current
Anything with a timer such as a water softner
Any wall wart from a radio, telelphone answer machine etc. still plugged in

Turn off breakers one at a time until the meter stops spinning.

Could be an attic light left on, or some other light in a crawl space or other space that is rarely visited.
