We have a split load consumer unit with all circuits apart from 2 protected by a RCCD. Up to now whenever the protected circuits trip it is a simple matter of resetting the individual CB However in the last few days we have had a couple of power outs which upon investigation have not tripped any of the CB's The power went of and then came on again after around 30 seconds or so I had initially thought this was down to the power company but this last time my wife who was in the extension server by a non protected circuit says that her supply was unaffected I has assumed that once tripped the CB would stay that way until manually reset Is this correct please and is my wife mistaken Could it be other than a power cut
Many thanks
