M.E.M. R.C.D. Tripping Off.

Zoomup
Mornin' All,

                      on this mild still spring type morn.

Do you remember the M.E.M. type R.C.D. that had a three position switch?


TOP POSITION = ON,


MID POSITION = TRIPPED.       LOWEST POSITION = PUSH SWITCH DOWN FROM MID POSITION BEFORE PUSHING TO TOP POSITION TO RESET TO ON.


Many months back I had a problem that when the customer turned her oven OFF it tripped the R.C.D. to OFF. (Read that carefully).


A new R.C.D. seemed to solve the problem.


Last week I came across exactly the same problem. Now that  a new R.C.B.O. consumer unit has been installed all is o.k.


Any ideas as to why this situation exists?

    A little more detail required. 


    What does the oven thermostat switch?

    Turning the oven off. How? By the temperature control switch? By the associated appliance switch. Is it part of a stand alone cooker?

    First case. The temperature control switch did cause the oven to trip the R.C.D. to the tripped position. I witnessed this happen, but it did not trip the R.C.D. every time, just occasionally. I believe that the first appliance was a stand alone cooker, the second more recent one was just an oven on its own, and the temperature control switch caused the problem.
