I had an old Wylex Consumer Unit which had wired fuses. (2x 30A and 2x 5A)
I replaced the fuses with plug in MCBs (from Wylex) (2x30A and 2x5A).
However, one circuit tripped when i used a device (eg Vaccuum) even though i have replaced plug in MCBs of the same A rating.
I subsequently replaced this particular plug in with a higher A rated MCB and it works fine.
Again, when i tried the cooker (on another circuit) it tripped the 5A MCB.
I think i have made a mistake while replacing the MCBs and may have replaced lower A MCBs in the wrong places.
Is there any way to check the rating of a circuit and place the correct A MCB in the correct location?
