Hello,
I have a brand new Indesit standalone ceramic hob oven installed with own mcb and new wiring (surface trunking) and cooker switch and socket both neons. The ccu is part rcd protected. The mcb is not on the rcd side. When power is applied to the cooker, the time flashes 0.00 and then I set the time. When any of the hobs are switched on, the rcd trips. Switching off the hob, the time is reset to 0.00. Tried resetting the time 2-3 times but when any of hobs switched on, rcd trips again.
Checked the voltage to the cooker switch =240v. With the cooker disconnected, v=240 on the load side (cable unplugged) indicating the neon is also not causing problem. With the cooker plugged in, the load side shows the voltage has dropped to half.
Called indesit and they sent an engineer (who said his son was part P, can't remember whether he was part p or not or even qualified electrical). He immediately blamed my wiring as a short circuit. I mentioned that if there was a short, the mcb will not come on even without the appliance connected, as it was possible to switch on the mcb. He did the testing on this meter, when circuit not on and insulation resistance was 999, When the appliance is connected its less than 1. On his notes he mentioned it was meant to be more than 3 minimum. (the minimum is 1M, but I didn't tell him). He then blamed mcd and cooker switch (both changed and it still the same problem. He also said the appliance will work off a 13A plug (the manual recommends a minimum of 32A). :cuss:I think Indesit needs to vet and train their engineers!!!!! and tell them to read the manual before attempting to service their appliances.
Its a hager board with neutral bar coming out of the rcd for all circuits, rcd and non rcd. Can this be the problem? Rcd will only trips if there was earth leak, True?
Any help appreciated?
Thanks
