Standby generator questions from Branchburg homeowners
Will a 22 kW generator run an entire Branchburg house?
For many homes, yes, but that does not mean every load can run at the same moment. Houses with two central air conditioners, electric heat, EV charging, pool equipment or electric cooking may need load management or a larger machine. The answer comes from a load calculation rather than from the phrase whole house.
Can a generator go under a deck?
Only if the specific installation satisfies every requirement for overhead clearance, airflow, exhaust, fire separation, carbon-monoxide safety and service access. Because the applicable guidance commonly requires substantial overhead clearance, many ordinary under-deck locations will not qualify. It is a site-specific review rather than a standard placement.
Does the generator need its own gas shutoff?
The fuel installation has to include the shutoff arrangements required by the adopted fuel-gas code and by the installation instructions. The valve must be positioned where it is accessible, both for servicing and for isolating the machine in an emergency.
