Seems very odd. Out of interest where was the extension lead plugged in... was it plugged into a single phase circuit on a 3 phase system?
Did you verify the voltage of the extension lead between all conductors?

Poor neutral connections can present themselves as reverse polarity and cause higher then normal voltage to run through the coils. Maybe the problem is with the existing circuits.
 
Yeah was a 13A plug that was wired to a Dura plug, the Dura plug live had been wired incorrectly as I tested it after and there was reverse polarity, I took it apart after and the lead was wired wrong

The Dura plug lead was plugged in to a an extension lead had been used to charge batteries etc for two weeks
 
Did the fuse in the extension lead blow?

I'm struggling to see how it was a high-current fault and beginning to think it is the FE that can't stand long-term reverse power. Which is odd as the last measurement I did (by accident) suggested no real issue in terms of dissipation on a open neutral sort of fault.

No fuse didn't blow, breaker replaced and all working and tested fine now
