ISB Sola Basic Corrector de Voltaje

Roca Azul has wiring problems in the park.

I was at Roca Azul last winter when the electrical problems presented. A caravan from Quebec arrived with 22 large newer motorhomes. Probably too many of them were running too many things - air conditioners etc. The main entrance panel on the main power pole basically exploded - up in flames - flames shooting out - fire trucks arrived - not uncommon for RV parks in Mexico - this is my second experience with this. So they had to replace almost everything on the main pole - the meter melted - wires up to the power lines burned up etc. I forget exactly the numbers now but I believe there were 3 - 75 amp breakers in the box - 3 legs of power from the main power lines above (transformer) - I would guess 3 phase transformer. Anyway - they just put in new parts and instead of the 3 - 75 amp breakers they put in 3 - 200 amp breakers. The problem is the wires in the ground going from there to the different areas of the RV park are not large enough to carry that kind of amperage. So now the wires underground in the park are the weakest link and not the breaker so nothing is really protecting those wires. If a big caravan of big rigs comes in again and heats things up enough the wires underground will be burning up instead of the breaker box. This should not hurt you but could be very costly for the owners of the park as all new wiring might be necessary.

As far as polarity at Roca - as far as I know it is totally fine - never tested an outlet there that was not correct. We have stayed there quite a few times in several different spaces and I have tested all the spaces we have used and they were all wired properly.

Again - I have no idea what you mean about how you wired your ISB. But you said you wired BLACK to NEUTRAL and BLACK coming from a properly wired outlet is going to be HOT. NEUTRAL means pretty much what it says - no power on that wire - NEUTRAL. HOT should never go to NEUTRAL. I do not know for sure what you have done to test inside your RV or what you mean by that. But if you have wired BLACK to NEUTRAL you are not properly wired and could have serious problems. If you do not know for sure do not guess. Get someone who really knows to check. Do not guess that the plug in at the outlet is right or wrong - test it - check it - to know for sure. That is where any rewiring should be done - the park outlet needs to be wired properly - and never a need to be rewiring your ISB. I can only go by what you have written here and if you wired BLACK to NEUTRAL you have done it incorrectly. Perhaps you have used to wrong terminology or are not really sure. Please do not guess about this. Never ever guess about electricity if you want to live a long and happy life. If anyone is telling you it is OK to wire BLACK to NEUTRAL they do not know what they are talking about and are going to get you killed.
