A 24/22.5 kW Generac standby generator:
In November 2026, Green Sun Energy Services installed a Generac 24/22.5 kW natural gas standby generator at Pete’s home in Highlands, NJ. The home is served by a 200-amp electrical service, and the system was sized for 3,200 square feet of living space.
The transfer arrangement is a managed whole-house setup using a Generac 200-amp Service Entrance Rated Automatic Transfer Switch with an integrated surge protection device (Model G0099280). When JCP&L power goes out, the switch detects the outage and signals the generator to start, then transfers the full load automatically. Because it is a whole-house configuration, Pete does not have to decide which circuits stay live — everything comes back on. Two Load Management Modules are wired in to handle two 60-amp devices. Here, those two devices are the EV charging stations on the property. If the generator’s demand approaches its limit while those loads are running, the modules shed them automatically and restore them once headroom allows, keeping the unit from being overloaded without any manual action.
The generator itself is the Generac Next Generation Air-Cooled model, Model 7261, rated at 24 kW on liquid propane and 22.5 kW on natural gas — here running on natural gas. Connectivity is built in: the unit includes cellular, Wi-Fi, and Bluetooth connectivity so Pete can monitor status and receive alerts remotely. The generator sits on a 5,000 PSI precast concrete pad (54″ x 32″ x 3″, 190 lbs). Installation included up to 20 feet of electrical work and 20 feet of gas plumbing. Grounding followed NJAC 5:23-3.16, requiring two grounding rods and an intersystem bonding bridge; a #4 AWG green-jacket copper ground wire was run to the system, and a #4 AWG copper bond was run from the water main to the service main. A 12-volt start battery is included with the unit.
The generator is covered by a 5-year limited warranty from Generac and a 5-year limited workmanship warranty from Green Sun Energy Services.
A 200-amp electrical service swap
As part of the same project, Green Sun replaced Pete’s existing electrical service. The work included a 200-amp, 120/240V service swap with a 40–60 circuit main lug load center fitted with standard breakers and feeders, and replacement of the existing 200-amp meter pan. The new panel uses the generator’s Service Entrance Rated ATS — with its integrated surge protective device — in place of a separate main breaker. The work is covered by a 5-year limited workmanship warranty from Green Sun Energy Services.
Pete also has a service plan in place that covers annual generator maintenance and an extended parts-and-labor warranty, so Green Sun will keep the system running and handle covered repairs going forward.

Standby generator questions from Highlands homeowners
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 do outages last longer on some Highlands streets than others?
Mature tree cover over overhead lines is the usual reason. Limbs coming down in wind, snow or ice take the lines with them, so heavily treed streets tend to see both more frequent outages and longer restoration times than open ones. It is one of the honest arguments for standby power rather than a portable generator.
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.
