Many looking into having a backup power system (from a generator or battery/inverter system) will quickly see they need a "transfer switch". This is one style for switching a large main power feed to a part of your house (with models available for 200 amp or smaller ones like I got the 100 amp size). With this kind of switch feeding a selection of your house circuits, you can manually select what circuits to turn on from your source and perhaps take turns on running things to still enable most, but not all at once to not overload the generator. I'll note there's other "transfer switches" with a bunch of small switches in a box available as well that may be better for you, but maybe this works (depending on where you want such). The purpose of all such "transfer switches" are to allow power feed from your choice of power sources (utility or generator/backup as the normal ones), yet insure the 2 sources are never connected.This box only has knockouts on the bottom, so all the wires will need to come in there (and be looped to the top for it's connections). If running 4 gauge or bigger wires (for 100 amp) they may be hard to bend around and fit (avoiding the moving lever that needs to move). I'm actually only running 40A wires, but haven't seen a smaller switch than this like it where this works. Obviously with manual switches will require you to go move it when the power goes out (and start the generator etc), yet you can have a good setup costing under $2000 versus ones with auto-start etc costing $5000+ just for the generator (where mounting etc can add to $10,000). Up to you on what to go with.
