I consider this dangerous advice.  If you have an ELCB tripping, you do 
not treat the problem symptomatically, by creating an unsafer system, 
you find out what the real problem is and you fix it.

I can't tell what the exact wiring configuration is here, but it is very 
likely that you have created a situation where there are pieces of metal 
in reach which have low impedance paths to very different "earths".
