Using the lowest wattage light bulbs that provide a safe level of light will reserve power for additional lighting elsewhere or for a small appliance. Remember that the greater the load on your generator, the more fuel it will use. Keep cords out of the way so they don't present a tripping hazard especially in dimly lit doorways or halls. Never run cords under rugs or carpets where heat might build up or damage to a cord may go unnoticed. Extension cords must be properly sized to carry the electric load.
Overloaded cords can overheat and cause fires or damage to equipment.
Transfer switches Use a transfer switch when connecting to a building's electrical system. Have a licensed electrician install the transfer switch. A transfer switch protects the lineman. This stepped up voltage, backfeeding through the utility lines, may electrocute workers that come into contact with the utility lines. Improper connections can allow the generator to overload utility line current when power is restored.
