So not much going on so I thought I would throw this out. On a periodic last week in a school we had two of the MK power tracks where you plug the sockets to them. Each track had an rcd enclosure with a 100ma, Wylex BS4293 rcd. The oddity is that the rcd enclosures have traffolyte labels fitted stating 50ma rcd, I thought nothing of it other than a 40 year old spelling mistake however when it came to testing them they tripped at half their rated current, 50ma in my eyes. There is no evidence of external additions, anyone had this before.
