Having fitted an main RCD incomer at a mates house, his oven is now tripping the RCD, every time its turned on, I suspect the one of the element is on its way out and is making the RCD operate, I havnt had chance to get to have a look yet, Has anyone got any advice on what to look for, The first check ill be doing is a few megger tests, so would it work if i was to test between the 13A plugtop and earth, with the oven in the on position, and if i find it flat down, then isoslate one element or other component such as the simple oven light at a time, to see if it alters the readings, I dont have too much experience on ovens
