I went to a friends house & she showed me what she wanted done on her property. I saw this work already done supposedly by an electrical contractor in the area. 200A panel w/100A wire (#2 aluminum). She said the electrician told her she only had 100A. This is true but where is the protection now? Am I missing something here? She either needs to switch the main breaker to 100A or upsize her service entrance wire to 4/0 aluminum. What she has now is not even close to being legal as far as I can tell. What do you guys think?
