Oven Element faulty.....or is it?

[catdog]

Hi guys.

Oven Element was knackered-open circuit. Just fitted new one last night-started to heat up the tripped rcd.....

Did IR to find between LN to earth was 0.45Mohms. Managed to get it back on again and thought might be able to blast out any moisture. It strangely heated up and the did an insulation resistance and it was then showing 0.2M ohms.

Took it out and this morn just did another IR and it is sitting at 45Mohms!

Was planning to return it but if they test it and it's 45Mohms.....

Any thoughts?!

I normally use an oxy-acetylene torch to get them hot, it's a bit quicker and safer than powering them up on a rubber mat with no RCD.
