Troubleshooting
What happens if you overload a generator?
Draw more than a generator can deliver and, at best, its breaker trips. At worst, you damage the generator and your appliances.
The sequence
- Overload protection trips. A well-made generator detects the excess and cuts output to protect itself.
- Voltage and frequency sag. Before it trips, output quality drops — hard on motors and electronics.
- Overheating and damage. Sustained overload without protection overheats the alternator and can permanently damage the unit.
How to avoid it
Size for your real peak — running watts plus the single largest startup surge — and keep total load under the rated continuous output. Remember that at altitude and in heat, the generator delivers less than its nameplate.
Common questions
What happens if you overload a generator?
The generator's overload protection should trip and cut power. Repeated or sustained overload without protection can overheat the unit, damage the alternator, and harm whatever is plugged in through voltage drop.
How do I avoid overloading it?
Size for your real peak (running watts plus the largest surge), and don't add loads beyond the generator's rated continuous output.
