Foca Se,
I would say that the posters you see here are simply into what they do, and find this a convienient way to expand their horizons.

To be honest, i read more than posted & many times have flipped back and forth thru the NEC completely befuddeled, such exersice is good, however frustrating.

It is not neseccarily the union or non-union sparky that is superior, although both sides could pose a good aurgument. It is the sparky that eats, sleeps, walks & talks his trade that is. As one of my instructors simply phased it,
" A good sparky keeps his nose in the book!"
so how many times do you see that happen at work, or at lunch, or after work???
