Never use a generator indoors — carbon monoxide from the exhaust is deadly.

  • Do not plug the generator into a wall outlet.
  • Use a licensed electrician to hook up standby electrical systems.
  • Main breakers should be opened to avoid feeding power back into Entergy’s lines and creating a hazard for the public and power line workers.
  • To prevent overloading your generator, add up the total wattage of all loads to be connected to the unit at one time. This total should not be greater than the unit’s rated wattage capacity. Allow 2 1/2 times the listed wattage for starting the indicated equipment.
