Back Feeding

Improperly connecting a generator to electric wiring can produce “back feed” – a dangerous current that can electrocute or critically injure you and others. Back feed onto power lines from a generator could create “hot” power lines during an outage.

Utility transformers then “step up” or increase this backfeed to 1000s of volts – enough to kill a utility lineman making outage repairs a long way from your house.

Electric generators can provide peace of mind and convenience as long as you follow all safety guidelines. Improper use or installation of an electric generator can cause property damage, serious injury and even death. Follow these safety guidelines when using a portable generator:

  • Locate your generator outside so poisonous carbon monoxide gas is exhausted. Fumes from burnt fuel can be deadly.
  • Make sure that you are standing in a dry place, and the generator is properly grounded. Keep the generator dry.
  • Never attempt to repair an electric generator; only a qualified serviceman should perform repairs.
  • Do not remove or tamper with safety devices; they are there to protect you and your property.
  • Many engine parts are very hot during operation; severe burns may result if touched.
  • Keep children away from generators at all times.
  • Do not overload the generator. A portable generator should be used only to power essential equipment or appliances when necessary.
  • Overloaded cords can cause fires or equipment damage. Do not use extension cords with exposed wires or worn shielding.
  • Do not run cords under rugs where heat might build up or the cord damage may go unnoticed.
  • Turn off all appliances powered by the generator before shutting it down.
