History of GFCI development

[gbeaumont (Gerry Beaumont)]

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

[FONT=Arial]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" :-k I can see it now “All students who went drinking last night please step forward” :lol: [/FONT]

I love the history of common everyday things …

Gerry,

If you haven’t allready, try wathcing a series called Connections or the sequel Connections 2 by Jame Burke (He’s British but you can still understand him) A very interesting series.

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