Generator extension cord vs household extension cord: Household cords can't handle generator loads safely

Generator cords use thicker 10 or 12 AWG wire and weatherproof insulation, while household cords are rated for light loads and risk overheating, voltage drop, or fire under generator amperage. Get a proper generator cord with locking connectors and the right plug (like NEMA L14-30) for safety. A $60–100 cord is cheap insurance compared to a burned tool or house fire.
