Evolution of the Quick connect [RE-wrenches]

William,

FYI. Note that most countries in the Americas with 60Hz service 
actually have adopted some version of the NEC into their national 
electric codes. These include El Salvador, Nicaragua, Panama and Costa 
Rica in Central America, as well as Chile, Colombia, Ecuador, Puerto 
Rico, Trinidad & Tobago, and Venezuela. In other Latin American 
countries where the NEC nor any other regulation is not adopted, the 
better engineering houses will typically follow the NEC anyway  for 
commercial installations (e.g., Honduras, Dominican Republic).

Of course, enforcement and understanding of NEC varies in these 
countries. Since few engineers in these countries participate in U.S. 
centric NEC committees, there is a little in-country understanding as 
to the reasoning behind NEC regulations. They are often few to no 
electrical inspectors in many places as well. Some of these countries 
also face severe problems with illegal electrical hook-ups (and sadly 
many young people are killed doing so). Thus, you still often see 
dangerous practices in some places which are severe fire hazards that 
unfortunately cost lives.

Nobody uses the NEC in Europe, they have their own regs.

Sincerely,
