We never run our generator each week.  However, we do a weekly inspection and visual check each day.  We also do a full load test once a month.  Is it common practice to run it each week?  If so, would running it without load for a minute or two be ok?


NFPA 110 doesn’t require a run each week (see attached below), but most owners do this anyway as a precaution.  Current practice is to run the generators unloaded for no longer than it takes for water temperature to stabilize and then shut them down.  Probably shouldn’t take over 5 minutes if thermostats are operating correctly.
