Why the peak is what matters

A generator doesn't stall on the running total — it stalls on the surge. The single largest startup spike here comes from the refrigerator. Add it to the running load of everything else and you get a 680W peak. Since that is under 3,000W, the generator handles it.

Common questions

Will a 3,000W generator run a refrigerator?

Yes. Running refrigerator, household lights (led) draws 360W continuously, but peaks at 680W when the refrigerator starts. A 3,000W generator covers that with room to spare.

What's the difference between running and starting watts?

Running watts is the steady draw; starting (surge) watts is the brief spike when a motor starts. Generators must handle the surge, not just the running total — that's why this calculation matters.
