Title: portable oven earth leakage trip
Post by: phaseform on April 10, 2016, 08:32:59 am

I've gotten a hold of a plug in oven which after working fine for a few days has tripped the RCD device. Now the RCD won't even switch back on. I'm not exactly sure about earth leakage principals, the device is showing a measurable resistance between one of the mains pins and the ground. I have disassembled the device and it seems both the top and bottom heating elements each show a measurable resistance to the earth pin. I'm assuming the oven is junk now?

I would say so. Howabout replacing the heating elements ?

Ehh I can probably buy one off Gumtree for $30 or find a better solution.
On another note I've evidently been in this waiting room over an hour

You can disconnect both ends of the elements, which will then tell you which one has the leakage. You can buy a replacement element if the oven is expensive, but for a cheap one ( cheapest I have seen retail is $15 this week, though it is barely big enough to get a dinner plate inside it) just scrap it.

If you find the faulty element you can get the moisture out of it by heating up with a small gas torch for a few minutes, getting it to over 200C for a few minutes will drive the adsorbed moisture out.
