Presumably the meter fitter was under the impression that the original DP isolator belonged to the customer rather than the supplier? (perhaps being generous there). It does feel a bit unhelpful to have left the new available terminals just of of reach of the new tails.

And I'm guessing that the other two phases have been left ready for the meter fitter to connect to the new 3P meter.... but he's just ignored them & only re-connected a single phase?

On second glance, it looks like the ends have now been taped up? So the whole reason for the upgrade to 3P has been overlooked.....

Naturally, the householder, who is an old friend, is not best pleased.

The only possible reason that I can see for positioning it so low is something to do with accessibility - rather like waist-high CUs. The top of the meter could so easily have been placed level with the switch-fuse.

Clearly with the isolator where it is, the 2nd and 3rd phase tails cannot reach. The electrician could easily have left longer tails, but as Andy says, they would then dangle with the other clothes line at the bottom of the board.

What alarms me is the SP isolator. If the 2nd and 3rd tails had been connected to the TP&N isolator, it would have been possible to isolate N (and one phase) from the 3-phase part.

I have warned my friend accordingly.
