Stephen from Barnegat, NJ has been a Green Sun Energy Services client since December of 2022. The generator was commissioned in March of 2023: 26 kW on propane, on a 150-amp service-entrance switch with a 100-amp smart management module and surge protection. Propane rather than natural gas is what a property without a gas main uses, and it is worth noting that the same machine is rated 26 kW on propane and 22.5 kW on natural gas – the fuel changes what the engine can produce. The load calculation asked for 20 kW across 2,000 square feet, with a well pump, two heat pumps, a sump pump, an electric oven and an electric dryer between them explaining the figure. About eleven feet of pavers were lifted and a trench run between the main house and the studio as part of the work, with a paving contractor reinstating them afterwards.

Standby generator questions from Barnegat homeowners
Does new gas piping have to be pressure tested in Barnegat?
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.
Which electrical code applies to a new installation?
Under the current New Jersey code cycle the Electrical Subcode adopts the 2023 National Electrical Code. Projects filed during a code-transition period are evaluated under the applicable transition provisions rather than assumed into the newer cycle.
Why does cold weather matter when sizing a propane tank?
Because propane's ability to vaporise falls as the outdoor temperature drops and as the liquid level in the tank falls. A supply that looks adequate in mild weather can struggle to support a large generator through a long winter outage if storage and vaporisation capacity were not designed for it.
