I have replaced our cooker element twice this year on our Leisure dual range cooker CMTG94 model because it trips at 150 Degrees.What could be the problem.

its nothing to do with heat,if the element leaks any more than 30 ma,then the rccd will trip,discon the oven from the ccu,romve the wires of each ring in turn and megger the ring,live to earth,neutral to earth,make sure you take all wires of the ring.or you will get parraell readings,check each one till you find the faulty ring

check all the elements with an insulation tester at the point it trips.A combination of elements leaking to earth can cause the issue.Also when was the house trip last tested?.
