Eric from Holmdel, NJ has been a Green Sun Energy Services client since February of 2021. The generator was commissioned that September: a Generac Guardian rated 19.5 kW on natural gas, sited outdoors beside the meter with a 200-amp service disconnect and a bisque trim kit to keep it looking deliberate rather than bolted on. The load calculation asked for 15 kW across the 3,152 square foot house, so the unit installed has real headroom above the requirement – which is what stops a generator running flat out every time it is called on. It is supported by annual maintenance, an extended parts-and-labor warranty, and monitoring we manage, so a fault is something we see rather than something the house discovers during the next outage.

Standby generator questions from Holmdel homeowners
Can the existing natural-gas service in a Holmdel 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.
Why can't a generator be wired straight into the panel?
Because a standby generator needs approved transfer or interconnection equipment so that it cannot unintentionally energise the utility supply. The transfer switch is one of the most important electrical-safety components in the whole installation, not an accessory to it.
Is every generator trench eighteen inches deep?
No. Eighteen inches is a common cover requirement for certain raceway installations, but it is not a universal generator-trench rule. The code table sets different minimum cover depending on the wiring method and where it runs.
