The overload trip is a function of both time and current. The more load you draw the more quickly it will trip. It is designed to trip to protect the generator not the loads. Again, a breaker in your main panel can give you a faster trip. If you only use the generator for backup power you can manage loads by opening the breakers for large loads that you don’t want to start without turning other loads off first. For example, the 802 won’t run an electric water heater with a lot of other things running in the house so you can open that breaker to prevent that load from getting dropped on the generator. If you need the hot water you can turn off other loads then shut the water heater breaker. That way there is never a chance that you will overload the generator. If you are still worried about sensitive electronics you could get a UPS to protect them. That will help with abnormalities in ulitity power as well. Also I have noticed when putting very large loads on my 803a that voltage almost never drops out for more than a fraction of a second but frequency will drop a lot. A lot of electronics (not all) can run fine as low as 50 hz because that is the standard frequency in some countries.
