Final answer:
The ESA conducts inspections to prevent both thermal and shock hazards, with a focus on compliance with safety regulations through devices like circuit breakers and three-wire system configurations.
Step-by-step explanation:
The Electrical Safety Authority (ESA) conducts inspections to ensure that electrical systems and devices adhere to safety standards and regulations to prevent both thermal and shock hazards. These inspections are crucial for enforcing regulations that protect employees at work, supervising the transmission of energy, and ensuring the safety of consumer goods. Part of their role includes investigating workplace accidents and enforcing workplace safety standards.
Circuit breakers and fuses play a significant role in preventing thermal hazards by interrupting excessive currents. In addition, the three-wire system is fundamental in guarding against both thermal and shock hazards, thanks to its configuration of live/hot, neutral, and earth/ground wires, which involves grounding both the neutral wire and the casing of the appliance.
It is also important to note that transformer applications in electrical safety are discussed under Electrical Safety: Systems and Devices, highlighting their role in the broader context of electrical safety.
