Lisa from Howell, NJ has been a Green Sun Energy Services client since August of 2019. The servicing of a standby generator another company had installed came to us that month, and in March of 2024 the machine itself was replaced with a Generac model 7290, rated 22.5 kW on natural gas against a load calculation asking for 22 kW. Most of the 5,200 square feet runs on gas – two furnaces, the cooktop, the water heater and the dryer – so it is the double electric oven that accounts for much of what the generator has to carry.

Green Sun Energy Services replied
Thank you, Lisa. Replacing a standby generator is a different job from installing one: the gas line and the transfer switch are already there, and the work is making a new machine fit an existing house properly. The 22.5 kW unit in Howell was sized around what the house really draws, a double oven included. Glad it went smoothly.
Standby generator questions from Howell homeowners
What happens if we add a heat pump, a pool or an EV charger later?
Any major new electrical load should prompt a review of the generator's capacity. A machine sized correctly at installation may no longer be adequate once substantial loads are added. Load management can often accommodate the new equipment without replacing the generator.
Is every generator trench eighteen inches deep?
No. Eighteen inches is a common cover requirement for certain raceway installations, but it is not a universal generator-trench rule. The code table sets different minimum cover depending on the wiring method and where it runs.
How close to the house can a generator sit in Howell?
For the air-cooled models covered by the manufacturer's listed installation guidance, the rear of the generator can be as close as eighteen inches to a qualifying structure when every condition of that listing is met. That eighteen inches is a tested installation dimension, not a zoning setback, and a municipality can require more.
