A permit is required for the installation/use of a generator. Contact the Building Department for further instructions. Note, while LIPA does not provide generators, we remind customers who have generators to use them safely: Always follow the manufacturer’s instructions. A generator should only be used outside on the stable ground and away from windows and vents to prevent deadly fumes from entering the home through an opening. Do not connect the generator to your home’s wiring. Power can flow out of your home into the electric system creating a hazard for crews working in the area. Do not use all appliances at once. Turn off some appliances to avoid overload.
