Agreed.  Here in the US a current(!) copy of the NEC (National 
Electrical Code) is an essential night-stand accoutrement.

And ditto on the isolated work-bench/radio supply.  Add to that a mondo 
UPS and a ferro-resonant transformer (of mass rivalling an upright piano).

Perhaps the most dodgy thing we radio people do (well, in an electrical 
sense) is create our own grounds willy-nilly, banging in copper hither 
and yon.  Making sure these don't become part (or even the best part!) 
of the mains ground is essential;  at least transformer isolating 
feedlines coming from such grounding arrangements is necessary to avoid 
this.

         73,

                 Steve
