I believe most of our forum, including me, would need to know more information such as the types of loads and whether, or not, they are considered continuous. You can almost never have TMI (Too Much Information). I did say "almost".

Yes, you can use 220.83 to calculate the existing load and make sure that the 20 Kw generator is capable of carrying the calculated load or use a load management system to bring the connected load to 20 Kw.
