I think this is an opportunity for you to sell him the European wall recep's that will go with the increased ampacity OCPD's and then change all his plugs on the audio equipment and recomend a larger power stabilizer device which you could mark up - all this goes for $$$ you know plus your mark-up. Plus he needs a second service for all this stuff Plus all the additional hours and all the stuff would have to be imported etc etc I see a very lucrative job for you - anyone who spends 6k on a resi panel well ...... a fool and his money!!
