I have done electrically work "pro-bono" for places in the Caribbean
and was amazed how "foreign" their ideas of proper "electrical standards" are from North American standards. I have had to deal with some really anal-retentive electrical
inspectors in the USA and joked that I would supply them with a free trip to the D.R. and let them see how the electrical
standards are outside the USA. They would instantly seize up and die of a heart attack (just revenge) as seeing wires of one color and size disappear into a wall and emerge as a different color and size. C/B's circuit interruptors, ground wires forget it - not used or considered necessary. Service
entrance disconnects - non-existant. And in the suppliers stores half of the "required" components are not available or sold - or used. The list of differences goes on and on to the point of being comical - and dangerous - but that is how these people have always lived and done it.
