Standby generator questions from Helmetta homeowners
Does a generator in Helmetta have to sit twelve inches above the flood elevation?
That figure should not be treated as a universal rule without looking at the actual property. The required elevation can depend on the flood-zone designation, the municipal freeboard, the Design Flood Elevation, Coastal A or V Zone conditions, NJDEP requirements and the applicable building-code provisions. Each flood-zone installation is worked out individually.
Can a standby generator run central air conditioning?
Yes, when it is sized for it. The design has to account for both the running demand and the starting surge of the air-conditioning equipment. Load-management equipment can be used where necessary so that demand does not all arrive at once.
How is the gas pipe size worked out?
From the generator's demand, the available pressure, the pipe length, the allowable pressure drop, the fittings, the pipe material and every other appliance connected to the system. The adopted fuel-gas code carries the sizing requirements and tables, and the model's published fuel consumption goes into the calculation.
