Classification code for 100ma TT 3036

[Deleted member 4632]

Hi all, carried out an EICR recently on a caravan. System is a TT with 4293 100ma main switch then into a 3036 board. All wiring tested ok with just a few damaged accessories to change. RCD tested ok but its not time delay. Should I be recommending additional 30ma RCD protection for circuits (in walls, bathroom and outside socket)?

You should Code them appropriately. Is there supplementary bonding to the bathroom?

if the existing RCD is 30mA why would you want to fit another?

The OP says 100mA.

No supplementary bonding which I have noted as C2. So I suppose that C2 would apply to absence of 30ma RCD protection too.

oops, misread OP. thing is, with a caravan, the site connection is usually on a 3omA RCD anyway. is this a static or a tourer?

Maybe if the sockets are likely to supply equipment outside...I would say it's likely the case being a caravan. Then you also have to consider the installation method and what code it warrants.

Hi - Reg 721.411.1 refers to Reg 415.1.1 which says 30mA and 40ms at 5x

Thanks all. Will code accordingly
