Built in cooker tripping

[allan]

Hi, I’ve been asked to look at a built in double oven cooker, apparently everything works ok but when both ovens are used it’s tripping the cooker mcb, any pointers?

[electrofix]

so from that I would infer that if either oven was used on its own its ok but as a pair it trips

if its as a pair then you may have 2 low resistance elements not enough on their own to blow the trip but add up to over 30mA when they are both on and hot
