Anybody use a generator?

[FIJI]

is a brand of "Generator Transfer" switch that is required by law (here) if you're going to use a generator. Too many ppl screw up and "backfeed" juice to the power lines endangering workmen and other neighbors.
It's not cheap, but not hard to hook up either

from their site

"A transfer switch makes using a generator more safe and convenient – no matter what size. The National Electrical Code mandates that a transfer device be installed with all standby power systems including portable generators. During a power outage, a transfer switch safely isolates those circuits using generator power from the rest of the house, so the danger of back feeding the electrical utility is eliminated. By installing a transfer switch with your load center and connecting a portable generator to the transfer switch, you can run selected appliances such as a furnace, well pump (which cannot be run with standard extension cords), sump pump, refrigerator, television, computer and more during a power outage, depending on the capacity of your generator.
