John from Farmingdale, NJ has been a Green Sun Energy Services client since September of 2021. The generator was commissioned in February of 2022: a Generac Guardian rated 19.5 kW on natural gas, on a 150-amp service-entrance switch. The load calculation asked for 17 kW across the 2,126 square foot house, with a double electric oven among the loads – the appliance that most often pushes a kitchen past what its size suggests, since two elements drawing together approach the demand of everything else combined. The generator is supported by annual maintenance, an extended parts-and-labor warranty, and monitoring we manage.

Standby generator questions from Farmingdale homeowners
Does new gas piping have to be pressure tested in Farmingdale?
Yes. Gas piping subject to the adopted fuel-gas code must be inspected and tested before it is accepted. New Jersey adopts the 2024 International Fuel Gas Code, which governs the inspection, the test pressure and how long the test has to hold.
Does the house run on the generator during its weekly exercise?
Not necessarily -- it depends on the generation of equipment, the controller and the configuration. Traditional systems commonly exercise without transferring the house at all. Newer equipment with current controls may support different exercise and transfer behaviour.
Does a 200-amp service need a 200-amp transfer switch?
A transfer switch installed in the service path has to be rated appropriately for the service and the configuration. A 200-amp service commonly uses a 200-amp service-rated switch, but the actual design is confirmed by the electrician rather than assumed from the service size.
