Default History of GFCI development

Hi to all,

I love the history of common everyday things all the more so if they relate to our profession. the following is a link to a great article on Mike Holts site

All about Professor Dalziel and the GFCI

All Mike's newsletters

Probably the best electrical site around; www.mikeholt.com

Regards

Gerry

Even then, research on the effect of electric shock on humans was a very sensitive area. Dalziel, using unique methods of persuasion, extreme care and rigorous methods of testing, amassed a large amount of data from a wide range of tests on approximately 200 volunteers of both sexes and a range of ages. These data provided an excellent source of information on the physiological effects of electric shock, and Dalziel soon became a world authority on the subject.
"using unique methods of persuasion" I can see it now "All students who went drinking last night please step forward"

He also does a series called The Day the Universe Changed which is also good.
