Disconnect load before stopping generator?
The topic says it all. This is in the rule book for several brands of generators. Its not in the book for my Yamaha, but Champion and Predator both mention it. So my question is... lets say you run...

With ship-board generators, unloaded spin down was a law, not just a recommendation. Gagging and surging from a stopped-up fuel filter was mitigated by placing a primary filter between the bulk and day tanks.
When a voltage regulator on a regular generator encounters <55 Hz it goes into "forcing mode" which tests regulator strength. The Delco H9000 regulator I love so dearly could withstand 20 amps of field current at 180 volts. This is rotor current nothing to do with generator current.
A mistreated component takes its revenge out by having a short lifespan.
My AC system controls are always placed chest-high including the breakers. I have sold aftermarket small generator voltage-regulators down here because owners simply shut off the generator and then wondered why it would not re-start unless the load was disconnected.
The custom with generator loading
Switch the largest load first upon starting
Then progressively smaller loads
When unloading
Switch off largest load first
Then progressively smaller loads.
If a Ferro resonant line voltage transformer is present
Switch it off first
