Portable Generator

It's hurricane season, you just heard the weather forecast & it's not good. You roll out your portable generator, fill the gas tank and start looking for your extension cords. You find and untangle your extension cords and then start routing them to the appliances you want to keep powered. You finally finish routing your extension cords, leaving some doors open because they cannot close and tell everyone to be careful, don't trip over the cords.
Worse than the above scenario, you connect your generator to your circuit breaker panel, to power your circuits when the power goes out. This is a very dangerous practice that can or injure linemen restoring power as electricity is back fed through the meter on to the power line.
