Head-scratcher

Doing an EICR that’s ‘interesting’.... found this. Installed by a solar outfit, it’s the first thing in circuit after the supply meter, feeds back into a pair of Henley’s doing the rest of the mess. L & N terminals are wired incorrectly - can anyone think of a legit reason for doing this this way? And so no... there’s also no protection to it or means of isolation.

That is a meter, probably for measuring the power exported to the grid from the solar installation.

I guess the same tends to be true of the supplier's meter in terms of no means of isolation or protection.
