RCD UPSIDE DOWN ?

garywwess

Hi All,  hmm,  i have a shiny box with a plug on it..  so far so good ..except the RCD is mounted upside down, i would have thought that generically speaking ALL switches for isolation or reset would have been “lift to reset” & trip down for off but cant find anything that backs this up.. but, the wording is also upside down on this one and on another where the wording is correctly oriented it clearly states up for ON when it is obviously the other way round (proved live).. 

any reference material you can point me too..

    Nah, both lower quadrant (down for go) and upper quadrant (up for go) semaphore signals fail safe (i.e. to horizontal stop/red/danger) when a cable snaps (they have weights on the arm itself to ensure that). The difference was more regional - the old Western region (and a few other places) stuck with lower quadrant until replaced with fangled electric light ones.

    Yes, well, there is more than one way to skin a cat. The fact remains that some way had to be found to make signals fail safe.
