Answer :
Final answer:
Power buggies must have controls designed to prevent accidental operation, thereby avoiding thermal and shock hazards. Safety devices like circuit breakers and GFIs are crucial for maintaining electrical safety and preventing serious risks associated with electric power.
Explanation:
All power buggies shall be provided with controls that are arranged or shielded to prevent accidental operation. This includes measures to guard against possible thermal hazards where electric power causes undesired heating effects, as well as against shock hazards which occur when an electric current passes through a person. Accidental operation can lead to such hazards, leading to severe consequences like electric shock or fire, due to a short circuit or other malfunctions.
To prevent such risks, electrical safety systems and devices are employed. For instance, circuit breakers and fuses interrupt excessive currents to prevent thermal hazards. Similarly, the three-wire system guards against both thermal and shock hazards, and a ground fault interrupter (GFI) prevents shock by detecting the loss of current to unintentional paths. These precautions are essential in ensuring that power systems remain safe and reliable.
