RCD's and vibration

Paul Brewerton

Where RCDs are installed in areas such as mobile welfare units, caravans, towable catering units, etc)

After being transported from A to B, are they likely to have suffered any detrimental effects (particularly due to vibration) caused during transit?

Case in question is self powered mobile welfare units we have on site, which are tested prior to delivery and found to be functioning correctly. 

Cabin manufacturers have stated that there is no need to test again, after every time the unit is moved, and indeed would be impractical and overkill in many instances, yet I have someone claiming that RCDs fail due to vibration. 

My gut feeling is this is nonsense, if an RCD is tested at any time and found to not function, how would it be determined that the root cause was transit vibration anyway?

    Would it be too much to require that the test button be tested on arrival? (And then recorded along with any other checks before the cabins are put to use.)

    Yes, that is exactly what we do. But I can imagine that in some instances 'ordinary persons' would not think to do this. Think of welfare being moved around at the side of a motorway project by a groundworking team.
