I want to install a stand-by generator in my house. Do I have to rewire the entire house.
In most cases you will not have to rewire the house. The average generator installation can be performed in one day. Most of the generators on the market today come with automatic transfer switches that will switch from your regular service to generator and back in case of a power failure. Also, many have “smart switches” that can help manage to load on the generator for better performance and safety.
