    I think some electricians still consider a first floor flat on PME suipply does not require RCD protection (as far as an EICR goes)

    My house has the original "fusebox" from when it was built in 1959
    There is a card with fuse wire on hanging next to it -left by the previous house owner

    and yes I know it needs updating

    I don't think that I have ever heard that one - can you perhaps give me some insight into their reasoning/thinking?

    Kind Regards, John

    Don't think I can vote. No RCDs except standalone board with RCD for shower only.

    Possibly assuming no sockets here can be used for outdoor use, perhaps?

    Maybe, but we are years past the day when it was felt that only such sockets 'needed' RCD protection.

    What often seems to get overlooked is that, contrary to common misconceptions, the main potential advantage of RCDs is not that they will trip if someone receives an electric shock but, rather, that they will often trip in response to an L-E fault which will not (or not for a long time) trip an OPD long before a person gets a chance to suffer a shock - and that scenario is at least as likely (probably much more likely) indoors as outdoors.

    Kind Regards, John

    I would say that more-or-less counts aa "Non"!

    One thing this poll has indicated is how important it is to spend a lot of time carefully thinking about the response options to bbe offered in a poll such as this.

    Kind Regards, John

    No, it's not non - can't say it's non.

    I'll pretend and settle for non except for outside sockets

    I don't really understand. I thought you said that the only RCD was for a shower, didn't you? If so, then why "non except for outside sockets", if the outdoor sockets don't have RCD protection (i.e. are not an "except")?

    Kind Regards, John

    Because there's no option for non except shower. Don't want to put just non, because there is one circuit that is RCD protected.

    Agreed, but nor is there a "non except outside sockets" (although there is the opposite - i.e. an "Only outside sockets").

    Non except outside sockets = only outside sockets.

    Doesn't it??

    Indeed - but, unless I've misunderstood you (to be saying that your only RCD was for a shower) then "only outside sockets" is totally wrong for your installation, isn't it?

    Kind Regards, John

    Yes but to put just non (or does he mean none?) is totally wrong too, as there IS an RCD, on an important circuit as a shower.

    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.

    Which I didn't consider earlier.
