Yes, I'm sure that he means 'none' - eric's typing/spelling is not known for being perfect.Yes but to put just non (or does he mean none?)...
Yes, I agree that it's wrong.. is totally wrong too, as there IS an RCD, on an important circuit as a shower.
All true - but I don't think (and it seems that you may now agree) that "outside sockets only" is a suitable choice when the actual situation is "shower only".My argument was that 'outside sockets only' implied just one RCD too - BUT on reflection, this could consist of several RCDs, either at the board, or, as I just realised, built into the actual outside sockets themselves.
Apart from anything else, whilst outside sockets (or sockets likely to supply outside equipment) have been required to have RCD protection for many years, unless I'm wrong (and despite what manufacturers of showers say), to the best of my knowledge there is actually no requirement (even today) for shower circuits, per se, to have RCD protection (although, per current regs, the cable may need such protection if 'buried').
That's why I thought that, although there was no ideal option for to to vote for, "Non" ("None") was perhaps the closest, since it seemed that none of your circuits which were required (by regs) to have RCD protection actually had it.
However, that was only my suggestion as to what vote might be 'least wrong'. Given that there is no "none of the above" option, not voting at all would probably be the most correct/'honest' course!
