Decide what works best for you

At Entergy, we are often asked what size generator is best. The answer depends on the expected usage, but 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.


  • Never use a generator indoors. Carbon monoxide from the exhaust is deadly.
  • Never plug the generator into a wall outlet.
  • If you plan to use a standby built-in generator, always use a licensed electrician to hook it up.
  • When using standby built-in generators, the 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.
