Weird?! Neutral-earth fault

Was it ever allowable on previous editions of regs?
I mean, for PV to share RCD with other circuits.
My own house, I had an MCS accredited installer for PV, and its just a breaker tagged onto the end of a split board. And ive seen many a number of customers boards done the same way.... as well as EV charge points just added into DB as well.... where ever there was space.

Yeah, interested to know the answer to this as well since i thought it was acceptable.

No, whilst it has not been specifically prohibited in the past it falls foul of the fundamental principles detailed at the start of the regs book.

Must be thousands of installs like this. No wonder so many company’s jumped on the solar bandwagon and just threw them in.

I’ll get mine changed when I eventually upgrade to an all RCBO board.
