Energized exposed prongs
The product configuration leaves a plug end exposed while it may be energized. CPSC treats this as a risk of serious injury or death from electrocution.
Backfeeding is not a safe shortcut
CPSC says using these cords to connect a generator to a home electrical system can expose people to electrocution and fire hazards. The configuration is a hazard, not a shortcut for connecting temporary power.
Multiple hazards can interact
The agency also notes that short cords can encourage generator placement near a building or enclosed area, creating carbon-monoxide danger. Electrical-product safety communication should therefore consider the full use environment.
