Dunno the brand - it came from TLC. Notice you can pay between about £25
to £80 for similar. Is this sort of failure common at the cheaper end?


I would say so.

Called out a few months ago to the horse sales in Doncaster. This was an
unheated room next to the vets office. In order to get the 2m distancing
they decided to use this room.

Two 10 year old unused RCD metal clad sockets had failed.

Just a tip on buying a new one Dave. Try to get one to BS7288:2016 and
not old stock that is to BS7288:1990.


From some light googling it would appear that BS7288:2016 devices are
not suitable for use in this situation. The standard says they are only
to be used as additional protection where there is an additional RCD.
