Anybody know the year the gfi outlet was first required by nec? I see that in 1976 the 5 milliamp rating was first introduced...

Re: history of gfi
I believe in 1971 any receptacle outlet within 15' of a swimming pool required gfci protection. I also believe there was a requirement for all exterior receptacles to have gfci, but that was not to be effective until Jan. 1, 1973. Bathrooms were added in 1975, garages in 1978. So on and so on....

I believe that the first GFCI's were a Class B type which were used for pool lighting. The had a higher current imbalance rating than the 4-6 ma ones we use today.

GG, excellent reference. I thought that the first NEC required GFCI's were for pool lights. Sometimes I wonder about my memory.

Thanks infinity. Paul, a book you may want to read is "Overcurrents and Undercurrents: All about GFCI's and AFCI's", by Earl W Roberts. I found it to be a very educational book with alot of information.
