Whether you are visiting, renting or buying a house in Mexico, you probably have questions and concerns about the electricity. I have lived in San Miguel de Allende now since 2010 – rewired two houses, and assisted with the electrical design and installation in a new house. I think I have seen the best and worst of electrical wiring here. This website started out describing the differences in electrical wiring and how to fix some of the more egregious problems. The result was a book that is now available as a free PDF download on the page A Gringo’s Guide to Mexican Wiring.
Other topics of interest to me are also contained on this website. These include expanded material on some of the information contained in the book such as the use of a transfer switch to improve load balancing with multiple electric meters, LED testing, etc.
