Advice on coding dual (RCD) Residual Current Device board

A colleague of mine had come across a dual (RCD) Residual Current Device board with no spd,a solar pv system and a car charger.

this was installed around 2 years ago when built from new.

my understanding is that the evse cant be on a shared rcd neither can the solar.they are both type A rcd and the evse seems to have pen fault and dc protection built in.

  • I came across exactly the same on a very recent new build ( moved in this year ) yesterday while fitting them an external socket.  

    The job couldn't possibly have been done any cheaper. The usual long meter tails from the meter box as well.
