I'm certain RQ hasn't used his household ground for grounding the
secondary but it might be possible to energize the ground-wire enough to
cause di-electric breakdown of the insulation of the cable (arcing to real
"ground") and thus give a path for moisture.. Oh well, propably not
something to consider especially as most high-power-coilers are using a
dedicated grounding.
