The seismic capacity for the equipment class of Engine-Generators (EG) maybe based on earthquake experience data. This equipment class includes a wide range of sizes and types of generators driven by piston engines. Turbine driven generators are not included in this equipment class. Engine-Generators are emergency power sources that provide bulk AC power in the event of loss of off-site power.
