You are not correct. My test showed that. Since you are a 'master electrician' I can understand your confusion.
A generator is turned by a mechanical device device such as a internal combustion engine or a steam turbine. Good design practice is too design generators, turbines, and nuclear reactors to exceed nameplate specification.
My first job after being a navy nuke was as a test engineer for GE. If GE turbines, generators, or reactors limited power productions, then lawyers got involved.
Later when the power plant demonstrated contractual performance, companies would sell services to 'uprate' rated power.
When it comes to small generators for RVs, the buyer should be skeptical of claims made by sellers.
My $88 generator purchased at Harbor Freight produced rated power. I measured it. Power produced was limited by the overload device.
When I saw the same generator advertised as a 1200 watt generator at a higher price, I was skeptical.
I replaced the overload device with one that would limit it to 1200 watts. By manually adjusting the speed I was able to get 200 more watts or a 1000 watts.
It is reasonable to assume that the generator can be rated for 1200 watts because it can supply the corresponding current without damaging the generator. However, if the engine is under sized it will not produce rated power.
Bottom line, when looking to buy a generator make sure the engine is not underpowered for the electrical rating.
