Just trying to point out that it's not electrical science reinvented its universal and the principles are the same. Slightly different methods of installation with different accessories but we use the same principles. If people understood the principles at home then they understand them here. If people can test properly in the UK which from experience is as bad there as it is here then they will be fine.
Just pointing out that a lot of people and I'm not saying you claim it is a completely different world and what it really was is they never understood what they were doing back at home.
