Still need some further info.
Nuisance tripping what is tripping?
Is the 100 mA RCD a S or time delayed as if it is not you will possibly have no discrimanation !
whats the layout of the board and circuits, sounds like a bad setup with disgrimanation between RCDS, can you discribe the layout more or poss pics?
edit,, sounds like you also may have a fault that needs to be found as well
100 amp feeding a 63 amp under board the feeding a dual Rcd board.
hmm as others keep saying, im a lil lost as well.. your saying 100 amp feeding 63 amp and then a duel rcd board? are you meaning to say... A 100amp 30ma RCD feeds a 63amp 30ma RCD then goes off to a duel 30ma RCD board? If you are then the whole install is inaproprate and needs looking into, we will then need to know more about the setup to see if any distribution can come off RCDs to stop the problem...
also to dig deaper, is it a TT system?
2 are in the board and the other is feeding that which is also being fed from a 100 amp rcd. cant seem to find any problems with cables and does just nuisance trip.
help plz
how long has this been setup like this? is it a new install? the setup seems a bit problematic and not thought through.. if its an old install i would be getting th IR tester out... if new i would be getting the install sparks out!
It's new . Last year . Yeah seems they have messed it up. It's been like this awhile but the install has never been used properly just now and thenhow long has this been setup like this? is it a new install? the setup seems a bit problematic and not thought through.. if its an old install i would be getting th IR tester out... if new i would be getting the install sparks out!
