Electrical codes in Ecuador

Don has been working hard on wiring the new house. The electrical conduit is concreted into the walls, floor, and ceilings. Over the last three years, as volunteer teams and local workers have come onto the site, they have all added their expertise to the house, but there was no overall plan drawn out on paper for the house, and non of the conduit is mapped. Good thing Don is a man of un-ending patience and farm-like fix-anything skills . . .
