What should be prioritized when designing electrical systems for safety?

When designing electrical systems for safety, ensuring redundancy in safety features is crucial because it provides an additional layer of protection against failures or malfunctions. Redundancy means that critical components or systems have backup systems in place, which can take over if the primary ones fail. This approach greatly enhances the overall safety of the system, as it minimizes the risk of accidents and incidents that could arise from a single point of failure.

For instance, if a primary safety device—such as a circuit breaker—fails, having a redundant safety device ensures that danger can still be averted. This is particularly important in environments where the consequences of failure can be severe, such as in industrial settings or when dealing with high-voltage equipment.

On the other hand, incorporating the latest technology, maximizing power output, or reducing human intervention, while valuable in certain contexts, do not inherently prioritize safety in the same way that redundancy does. Advanced technology may provide better functionality, but if it lacks adequate safety features or redundancy, it could still lead to unsafe conditions. Similarly, focusing solely on power output can compromise system integrity and safety. Lastly, reducing human intervention might improve efficiency but could also lead to a lack of oversight when manual checks or safeties may be necessary, thereby increasing
