John, I didn't think about that. Are GFI commonly used in the UK and Hong Kong or just in hospitals? Have the 230VAC GFIs in the UK evolved over the years from a once unreliable nightmare to a very reliable must-have device like in the US?
I have never heard any reports of GFI tripping with our products in the UK or Hong Kong, but being in the US, maybe any such problems are handled by our installation teams.

US GFIs wouldn't be acceptable, even if in fact they would work at 240 V. -- OOO - Own Opinions Only.
