Dodgy garage installation - borrowed neutrals?

Chris Pearson
This photo appeared in a car advert which was mentioned in a motoring forum.


The three lines all appear to make their way to the 3-phase board, but I cannot quite see why is happening to the neutrals.


Presumably the meter fitters were content that all was in order, although I suppose that the supplier's' principal concern is billing.


Would nobody give it a satisfactory EICR?

    As much as it pains me I have to agree with UKPN on this one, the property was most likely originally a single phase supply, then it has been upgraded to 3 phase. The top fuse is supplying the AMR meter which in turn is supplying one phase of the 3 phase board, The middle meter is supplying the bottom right hand meter which is supplying a single phase board  (not quite in picture) and another phase of the 3 phase board, the original supply is feeding the bottom left hand meter (you can still see the original top fixing screw for the original meter) which in turn is supplying DB3 and the last phase to the 3 phase The left hand neutral from the lower service head is in terminal 3 of the right hand meter, terminal 2 of the right hand meter is then going to the left hand meter wich in turn is going to a block underneath the cover of DB3, the right hand neutral from the service head is going to the AMR meter, that in turn is going to the block above the right hand meter. Kelly yes it looks untidy, but who would pay to tidy it up, as it is not unsafe.
