Hi All,

We had a new elec bill yesterday.
Their estimated was way off the actual reading.
On further investigation our meter is now running backwards!!
We dont have solar power or any other elecricity generating means.

About 18 months ago we had a new consumer unit fitted
with new tails to the meter from the main incoming fuse.

I wondered whether this had been wired incorrectly. Looking
at the cabling at the bottom of the meter left to right the 4
wires run as follows;
(from consumer unit) +ve, -ve, (from main fuse) -ve, +ve.
Is this correct? Anybody any ideas what is going on?
Would mis wiring a meter make it run backwards even?

They are coming to have a look in a fortnight but just wondered
whether anybody has any ideas?
Its very wierd...

It's been wired up wrong.

Should be:
Live (In)
Neutral (In)
Neutral (Out)
Live (out)

But, I'm amazed it runs backwards. Almost all manufacturers have a
mechanism to prevent that happening, as a deterrent against fraud.
