Congratulations! Well done!

Not bad, a totaly unexpected result I'm sure... one would think corona 
leakage for sure...

What sort of power levels are operating at? 5, 10KVA?

I also wish it was easy for us in Aussie to have 100Amp breakers 
installed into our homes... would make coiling alot better...

Has anyone is Australia managed to get those sort of current 
breakers/outlets installed?
 
Oh well, the 10amp ones will do for now, although, I managed to find a 
circuit with 2 outlets in phase and achieved 20amps in parallel.

Thanks for the info Bert, very impressed! Some photos would be nice!  
<hint hint> :-)

Catchya!
