Hi Guy
called to a oven tripping out the RCD.fault to earth found,got replacement element and installed.run up for about 4 mins then triped out the rcd.retested the new elemnt once it cooled down and down to earth.
got a replacement from the same place and this time before I go back , I have rigged it up at home,runed up again for about 5 mins glowed well and again triped.
it seems to have split slightly and again is now down to earth.
element is 1000W.
question is surely 2 in a row on on site and on straight of a plug top is a long shot to be bad luck.
any ideas

What sort of oven? If it is a fan oven, then it maybe designed to have the fan blowing on it when on. I had a "Friday afternoon" oven delivered new - a good make, but the fan and element connections were reversed. When the oven reached temperature, it switched off the fan - it should have left the fan on, and switched off the element!

Regards,

Alan.

Are the replacement elements manufacturer original parts or pattern/clone ones?

The element may have cracked as it is not designed to be on continuously without thermostatic control and fan cooling.

I'd buy another manufacturer's element from a different source.
It is possible that you have a bad batch or that they have become damp.

this new base element glowed nice.I take it the base element should glow like all other elements.
