Onan 4.0 BFA - Continuous Power?
Good morning, My searches have yielded little. Does anyone know or have access to specifications that tell the actual, continuous current that a newly minted Onan 4.0 BFA is supposed to produce?...

The NO LOAD rating of your BFA is 126 to 132 volts at 1800 RPM. The Governor keeps the Unit at 1800 RPM under any load. The drop in current from Loads will usually be no less than 122 volts at almost full load. The breaker on your Onan is 30 amp. But that usually means you can go as high as 33 to 34 before it trips. SPEED governs Htz and current output, hence the Governor to keep it at 1800. Newer (WAY NEWER) Onans have a Electronic regulator but still require the Governor. You can run 2 AC units with this Onan, BUT, that is about all. The problem is, 30 amp RV's rarely(almost NEVER) have 2 AC's on the 30 amp circuit. But the Onan can handle 2 if they do NOT cycle the compressors at the same time. Doug
