Dirk from Eatontown, NJ has been a Green Sun Energy Services client since March of 2021. The generator was commissioned that November: a Generac Guardian rated 19.5 kW on natural gas, on a 200-amp service-entrance switch with two smart management modules. The load calculation asked for 18 kW across the 2,208 square foot house, and a double electric oven is most of the reason a house that size needs that much – two elements drawing together approach the demand of everything else combined. A sump pump, two refrigerators, a washer, a gas dryer and a dishwasher complete the load. Annual maintenance, a ten-year extended parts-and-labor warranty and monitoring we manage all sit behind the machine.

Standby generator questions from Eatontown homeowners
How can a whole house be carried on a smaller electrical service?
Through load management. One or more large loads are controlled so they do not start at the same moment, or shut down briefly if generator demand climbs too high. That is what allows whole-house coverage where the raw sum of every connected load would otherwise exceed the machine.
Can the existing natural-gas service in a Eatontown home supply a generator?
Often yes, but the gas system has to be evaluated first. The review covers the generator's BTU demand, meter capacity, available pressure, regulator capacity, pipe diameter and length, and every other gas appliance in the house -- furnace, boiler, water heater, range and fireplace among them.
What happens if the manufacturer and Eatontown disagree?
The installation has to satisfy all applicable requirements. A manufacturer's listing cannot be ignored, and a manufacturer's minimum clearance does not cancel a municipal zoning requirement. Where requirements conflict or the interpretation is uncertain, the Authority Having Jurisdiction is consulted before the work goes in rather than after.
