Most portable generators really won't exactly 60 HZ over its range of light load to full load. If the engine is setup to run exactly 3600rpm and 60HZ at no load it will be slightly lower at full load. Most portable generators usually run at about 3700 to 3750RPM at no load so that it runs at 3600 at 3/4 load.
