We are experiencing electrical problems in our beach home, voltage is dropping and some of our appliances and pump do not work properly. We have notified CFE, and they were here twice but did not improve anything. What can we do?

Welcome to the club, unfortunately you are not alone. If you have a beach home sooner or later you will have this type of problems. Usually it is fluctuation in voltage that is responsible for all that misery and generally it is caused by lock of maintenance on the part CFE. Having a lot of experience dealing with them I can tell you that I have never seen so many incompetent people working for and managing one company, but as always, because it belongs to the government nobody cares and no one is responsible.
But the problem are serious and can seriously damage or shorten live of your appliances, pumps, and other electrical devices. One of the ways to prevent it is to install voltage regulators. Check your neutral wire and the grounding. CFE’s new digital service meters have problems but if you have one of the old models you should be O.K.
If the problems occur kip calling CFE for service and if after the first visit you problems are not resolved, do not call locally, and use their 800 number in Mexico City that usually gets their attention faster.
Good luck.

Hi
The line voltage in Mexico is higher than in the United States or Canada and could damage or greatly shorten the life of equipment built to US or Canadian specifications?

We had two computers burned in our home in Merida; also our friends in Telchac Puerto lost several of their appliances, due to a voltage fluctuation.
Use voltage regulators - You can find them in Home Depot, Office Depot, Sam’s and Wal-Mart in Merida.

Voltage regulators are rated in watts. To determine the right voltage regulator for your appliance, first find out the voltage 110 or 220 Volt AC and wattage rating watts or amps information on the back or bottom of the appliance or from instructions of an appliance. If no watts are shown and only amps are shown, multiply the volts input AC by the amps to find the watts.
