tripping rcb

[jmkl01]

i had a new electric hob fitted a couple of months ago , it was connected into the origional wiring and it worked fine but now it just trips my rcb all the time , i connected my old hob back up and it works fine, is there anything i can check with the new hob, the mcb doesnt trip it is just main rcb

 

[who took my fluke?]

since it is only the new hob that is causing the problem, it would suggest the fault lies there.

have you got access to the cable that supplies the hob? check to see it is not damaged otherwise i would say take the new hob to a repair shop.

is there anything i can check in wiring in the hob itself rather than having to send hob away the wiring outside looks ok

you could check the termiantions inside the hob but only do this if you can be sure you can put it back together! just check that the live neutral and earth terminations are free of each other. maybe you could replace the cable from the cooker socket to the hob??

Maybe the hobs draw different amounts of current? The old one didn't trip because it didn't draw above x amps, the new one trips because it draws above x amps?

What are the ratings of each?

dont know what the old one is but the new one is 26.1 total amps
