Article C5.21
ERS General Electrical Safety
Chapter: C5
In Simple Terms
F1 cars have complex electrical systems that power the hybrid engine. This rule ensures that if any single electrical component fails, the driver and marshals can never accidentally touch a live (powered) electrical part that could harm them. Even in worst-case scenarios, the car must be designed so electricity can't hurt anyone.
- No single component failure can expose anyone to live electrical parts
- All ERS components must be safe during normal operation and foreseeable malfunctions
- Safety applies to both drivers and track marshals/personnel
- Electrical hazard prevention is a mandatory design requirement, not optional
Official FIA Text
A single point of failure of the electric system or ERS cannot result in a person being exposed to a Live Part. The components used cannot cause injury under any circumstances or conditions, whether during normal operation or in reasonably foreseeable cases of malfunction.
