    Trouble is if we try and use it onto a non RCD protected house that has a fault that keeps tripping the device.
    That could be interesting!

    Yes, they'd have to ask the neighbour to reset the RCD!

    PS Does the Restore plastic box meet the new requirements for fireproof enclosures?

    It'll be sealed if for no other reason to prevent the neighbour switching it off





    Er, well, um, nope! :LOL:

    On that subject don't expect to suddenly see hords of metal cut-outs or meters coming into use, they can be a bigger safety risk than not!

    Hmm, looks like a plastic box, RCBO, and a length of cable. Bet it costs more than that shopping list !

    Have the rules changed then ? Before I was interested in such things, we had a fault at home - and for a while we had a supply from next door. AFAICT from things my dad said when it came up, they just installed a pair of cables from next door's cutout.

    I see the point in current limit of 40A just to keep everything running but the RCD at 30 mA is just asking for problems.

    We have all seen where we fit new consumer units and the RCD will not hold in on one circuit having one for all circuits you will be visiting every 5 minutes to reset the RCD.

    We know, and there have been representations to advise on the additional risks of this new reg. At the moment, that's what we have got.

    My MIL had a supply outage due to damaged cable under the house and the engineer dragged a genny out of the van and length of SY cable with RCD etc. Connected it all up and the RCD kept tripping as the original installation had no RCD and clearly a fault. Ended up just a trailing socket with a 4way for the freezer, boiler and couple of lights.

    Why does the box need to have an RCD in it in the first place?

    My house has an RCD incomer which I inherited. It was fitted in 1992. It tests out fine (Hager) and has only ever tripped due to known faults (flood under floor saturating junction box and faulty tumble drier element).

    To protect a temporary installation of a trailing cable at risk of potential damage.

    I can think of a few reasons.

    1: introducing a long (25m in the default kit but they say extensions are available) extra peice of relatively thin cable (6mm, presumablly chosen so the size/weight is managable) will make the EFLI higher, this may mean that overcurrent protection devices no longer provide adequate earth fault protection.
    2: the default cable appears to be un-armoured (again presumablly to keep the size/weight managble, they say a braided cable is available as an option too) and is likely to be routed in a less than ideal manner. RCD protection seems a reasonable precaution to reduce the danger in the event of damage to said cable.
    3: the kit may sometimes be used on TT setups where overcurrent protective devices are incapabale of providing earth fault protection so a RCD at the origin is needed.

    It would be good to see a bypass on the RCD, so the supply authority chap could, if the RCD wont hold, make a judgement call about whether to bypass it or to give householder a temporary board with a few sockets on it

    Do I take it that you can see both pages/'sides' of the brochure? I can only see the first page/side, the second being blank.

    Kind Regards, John
