The IBC has replaced regional codes in most jurisdictions and incorporates strong provisions regarding seismic and wind performance of electric generating sets that construction professionals need to understand. Generator sets are most susceptible to earthquake-related damage at the points where components – including the engine exhaust system, fuel lines, AC power-supply wring, load wiring and control wiring – interconnect. These connections must be flexible, so relative motion can be absorbed without damage. Without this flexibility, the building or generator set may be damaged and the generator may fail while in service. Additionally, when vibration isolation is required in a seismic application, seismically certified vibration isolators must be used to ensure the generator set isn’t dislodged from the building structure during the seismic event.

The International Building Code (IBC) is a set of rules for engineers working with generating equipment and supervising its installation. It addresses both the design and installation of building systems, with an emphasis on how those systems will perform in emergency situations – and continue to perform after such event.
