MikeSkyrme: The description sounds more like the meter capability than the system you have installed.
Best way to check is to count how many wires come into the meter box. Do you have a photo?
vinnieg: Looks pretty standard to me, are you renting a place? or sharing power costs with another unit? If so, just looks like a way to tell how much you've used.
Although to be sure, check your garage or shed and see if there is a large power point in there for industrial machinery...if not, then you won't have it
nakedmolerat: i believe that is 3 phase ^
mattRSK: Correct, that is a 3-phase system.
