Linda from Farmingdale, NJ has been a Green Sun Energy Services client since August of 2021. The generator was commissioned in December: a Generac Guardian rated 19.5 kW on natural gas, sized against a 19 kW calculation for the 2,861 square foot house, with a double electric oven doing much of the work in that figure. This was a new house, and the arrangement was set out plainly in the contract: the home builder would supply, permit and install the 150-amp transfer switch, and Green Sun would fit the generator to it. Two contractors on one electrical system is where jobs go wrong, and the way to prevent it is to write down which one owns which part before either starts. Annual maintenance, an extended parts-and-labor warranty and monitoring we manage all sit behind the machine.

Standby generator questions from Farmingdale homeowners
Why do outages last longer on some Farmingdale 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.
Can a standby generator be installed in the garage?
No. Residential air-cooled standby generators are designed for outdoor installation and must never be run inside a garage, basement, shed or any other enclosed occupied space. The engine produces carbon monoxide, which can cause serious injury or death. That is why outdoor location and separation from building openings are treated as critical rather than as preferences.
Does a permanently installed generator need a disconnect?
Yes. Permanently installed generators fall under the disconnecting-means requirements of the National Electrical Code's generator article, and the equipment and electrical design have to satisfy those requirements alongside the machine's own listing and instructions.
