Standby Generator Installation
A 22 kW Generac standby generator:
Keith in Red Bank, NJ had Green Sun Energy Services install a Generac 22/21 kW air-cooled standby generator in September of 2026. The home runs on a 200-amp electrical service and the system was sized for 1,600 square feet of living space. Fuel is natural gas.
The transfer arrangement is a managed whole-house setup using a 200-amp service entrance rated automatic transfer switch (Model G0099280) with an integrated surge protection device. When JCP&L power goes out, the switch detects the interruption, signals the generator to start, and transfers the entire load automatically — no manual steps, no choosing which circuits to keep live. With no appliances flagged for load management and no AC tonnage to shed, the generator runs the house as it normally would.
The generator itself is the Generac Model 7260 Next Generation air-cooled unit, rated at 22 kW on liquid propane and 21 kW on natural gas. It ships with cellular, Wi-Fi, and Bluetooth connectivity built in, so Keith can check status and receive alerts from a phone without being home. The unit sits on a 5,000 PSI precast concrete pad (54″ × 32″ × 3″, 190 lbs) and starts on a 12-volt battery.
Grounding compliance under NJAC 5:23-3.16 required one grounding rod and an intersystem bonding bridge. The run also called for #4 AWG green-jacket copper ground wire from the water main to the service entrance main, along with #4 AWG copper from the water main to the service main — both estimated at roughly 20 feet of electrical and 20 feet of plumbing work included in the package.
The installation is backed by a 5-year limited warranty from Generac on the equipment and a 5-year limited workmanship warranty from Green Sun Energy Services. Keith is also covered by a Green Sun service plan that includes annual maintenance visits and an extended parts-and-labor warranty.

Standby generator questions from Red Bank homeowners
Can the platform height be read off the FEMA flood map?
Not necessarily. The map matters, but it may not carry every elevation the platform design needs. An Elevation Certificate, a surveyed ground elevation, the Base Flood Elevation, the Design Flood Elevation, the local freeboard and the municipal flood ordinance can all bear on it, so the height is calculated for the specific property.
What is the main line circuit breaker on a generator?
It is the generator's primary AC output breaker. Worth knowing because if it is open the engine can run without delivering any power through the transfer system -- a machine that sounds like it is working while the house stays dark.
What gas pressure does a generator need?
It is model-specific and has to be read off the specification sheet rather than assumed. A current 22 kW model, for instance, specifies a minimum natural-gas pressure of 3.5 inches water column. Different models carry different requirements.
