8kw standby

[CTnative87]

So my aunt bought an 8kw gen. And the ahj asked me to do a load calculation. She only wants a couple of circuits like refrig, bed outlets , couple lights and well pump. I’m somewhat confused on what I need to do to calculate. Do I take the total amps x the volts(breaker that feed transfer switch) and then divide that answer by 1000 ? And that will be my kw for the exact amount the gen can handle in which that is what the ahj is looking for ? Need help if I’m wrong in the way im thinking

Please present your initial calculations. We will tear it down to manageable bits there after.

I haven’t done a calculation this is my question to which way I should go really

Is the transfer equipment automatic or manual? A load calc is only really relevant if automatic. See 702.4(B)(1).

Yes it’s automatic , Briggs and Stratton

Do the same load calc you would do for any house.

It’s for just 8 circuits lol

Then do the calc for what's on those 8 circuits. Only count the square footage of rooms with lights or plugs powered by those 8 circuits.
