Bidirectional RCD socket or RCD FCU, are there any?

[ericmark]

On another forum someone wanted to fit balcony solar with an old Wylex fuse board with MCBs fitted, it was pointed out to have 230 volts outdoors it needs RCD protection, but I simply could not find a single FCU or socket with an RCD which says bidirectional.

If the someone has money with which to buy 'balcony solar'' kit, it sounds that there are probably much more appropriate ways he could use the money to 'upgrade' his/her electrical installation

.... I simply could not find a single FCU or socket with an RCD which says bidirectional.

That's hardly surprising, is it? Until these recent discussions about what may become legal to use in the UK in the future, there was absolutely no reason why anyone would have wanted/needed a 'bidirectional' FCU/socket, so it would be fairly unlikely that anyone would have felt it appropriate to manufacture any ('speculatively'), wouldn't it?
