We used to lose power often. Last winter we had a Generlink installed on our meter. It allows me to safely attach a generator at the meter. My generator is a Generac 5000 that surges to 8000. The electrican said that we can run our house on it if we have no 220 devices on. I don't know if I could run a water heater or clothes dryer if all other things are off. But it beats setting in the dark with no tv, etc. No power loss of course since installation.
