Comicion Federal de Electricidad and shows how they wire, this is for all of Mexico.
Fully understood that there is a code in Mexico - just as there is in the US - and Canada. There is probably another book that shows how each building should be wired with complete written specifications. The problem in each country is that not all wiring is done by professionals or up to code. I have seen far too many improperly wired RV parks. Even the wiring shown in this book can be done improperly. In one of my previous posts I mentioned they replaced an old 70 amp breaker with a 200 amp breaker. The 70 amp was the correct breaker for the size wire they used. When the put in the 200 amp they might as well have put in solid wire with no protection at all. The breaker no longer matters because it was way to large for the circuits it was supposed to be protecting. And this book shows the main entrance wiring but not each space wiring. We have seen wiring in pedestals in places where they do not use properly colored wires (sometimes we see all black wires or all white wires - no way to know which is which). Then they may have a ground wire at the entrance panel but do not run a ground wire from there to the pedestals. And improper gauge wire - too low - is common. Poor wiring in RV parks can happen just about anywhere - as the survey I posted clearly indicates.
