Can a 2000-watt generator run a circular saw?

Sometimes, but it depends on the saw’s startup surge and how hard the tool is working. A smaller generator may run a circular saw under light conditions, but thicker cuts or added loads can push it past its limit.

Can a portable generator run a table saw?

Yes, but table saws usually need more headroom than smaller tools. Startup surge, heavier cutting, and running multiple loads at once can quickly expose an undersized generator.

Do power tools need startup watts?

Yes. Many power tools with motors need extra wattage when they first start. That startup surge is often why a generator that looks adequate on paper still struggles in real use.

Can I run power tools and a refrigerator at the same time?

Sometimes, but you need to add both the running watts and startup surge together. This is exactly why a load calculator matters before buying or connecting a generator.

Is an inverter generator enough for DIY tools?

For lighter DIY use, battery chargers, and some smaller tools, yes. For heavier saws, air compressors, or multiple simultaneous loads, a larger conventional or higher-output generator is often the better fit.

Why is my generator running but not powering my house?

This usually means your generator is not connected to your electrical panel. Running extension cords only powers individual appliances, not your home circuits. A proper setup requires an inlet box and interlock or transfer switch.

Do I need to turn off the main breaker when using a generator?

Yes. The main breaker must be turned off before turning on your generator breaker. This prevents backfeeding electricity into the grid, which is dangerous and illegal in most areas.
