Mbains,
Listen to Terry what he said above.
Using 7KVA and sitting on/actually serving as TC
terminal ,insulated of course, dissipates  HF energy
mostly in air corona impedance.but still few houndreds
of watts are  dissipated directly in a body anywayz.
WHO research data on this issue says that 800 watts of
RF Mhz power dissipated on way legs-arm is very
dangerous for average person (long term damages).
Where line should be drawn you be the judge.
As concerns drawing out connected arc to ground in
this case ,not even think about it-result would be
injury or death.
Always,and again all this is RF energy.Leathel one.  


Safe coiling to you,
Regards,
Boris
