In order to prevent damage to a portable generator, always:

• A. Run with all equipment plugged in
• B. Start with load attached
• C. Start and run with all devices connected
• D. Avoid starting it with equipment plugged into it and turned on

Answer: (D)

Starting a portable generator with a load already plugged in and turned on creates a large inrush current. That sudden surge can exceed what the generator’s electrical system can safely supply, causing voltage spikes or dips, overheating of windings, and potential damage to both the generator and the connected equipment. By starting with no load and letting the generator stabilize, you ensure the output is steady and within its rated capacity. Then you can add devices gradually, plugging in and turning on equipment one by one after the generator is running smoothly. This practice protects the generator and the devices from harmful surges.
