My mother in-law is building a house in Mexico. I already did the wiring in the house and we have to run the service feeds from the meter 150' away. We have a 200 amp panel and I am going to run it underground on a 2" conduit and are going to use 4/0 aluminum. My question is do I need a breaker @ the meter and @the panel? There is no way to put a breaker in the meter box so I have to put it on a junction panel of some sort. Any suggestions on the best way to do this?
