I don't have a functional whole house generator, but I fail to understand the silliness of extension cords......I do have an old hot tub line going out back patio though, covered, and it could very easy backfeed to the main panel....so if I needed to, just flip two breakers, main and the line to the genset.....and start the genset.....it's only a ~40 amp circuit, but it could carry the HVAC system for overnight, and the stove/range is run by BBQ gas.....
