Have a Rangemaster fully electric cooker installed in 2004, all have been well running off an old fuse wire CU, but have just had a new MK 10 way CU installed so now I have an issue with the RCD tripping which I have traced to the cooker.
The system worked well for several days, then out went the RCD, switched back on and all was well for another few days then out again, this time I could not engage the RCD with the cooker switched on so turned off at the main cooker switch and everything is fine. Left overnight and the cooker could then be switched on OK , went through the various cooker components one at a time and all worked OK without tripping, used two hobs to cook a meal then about two hours later out goes the RCD with the cooker only running the LCD clock. Thoughts as to what is going on here please!!
I have seen a few ideas on here reference running the cooker either from the non RCD side of the CU which seems a bit odd, or installing a higher value 100ma RCD for the cooker only, which seems to defeat the object of having an RCD in the first place?
FYI cooker is a Rangemaster Classic 90 Ceramic 230v and was new in 2004 total rating with everything operational 14.8KW. House was rewired back in about 1980 so running mostly on 30a cable from that time with newer from switch to cooker
