The metallic parts in an electrical system are bonded together to ensure proper overcurrent device operation, complemented by ground fault interrupters and isolation transformers. Circuit breakers and fuses are critical for interrupting excessive currents and preventing thermal hazards.
The metallic noncurrent-carrying parts of an electrical system are bonded together to ensure the proper operation of overcurrent devices in the event of a ground fault. This bonding helps maintain a safe electrical environment by facilitating the functioning of protective devices when needed. For example, in the presence of a ground fault, bonding ensures that the current flows appropriately to trigger overcurrent protection mechanisms.
Ground fault interrupters (GFI) and isolation transformers are other safety mechanisms used to prevent shock hazards. GFIs detect loss of current to unintended paths, while isolation transformers insulate devices from the power source. These components play crucial roles in enhancing electrical safety and preventing accidents.
Circuit breakers and fuses are essential in interrupting excessive currents to prevent thermal hazards. By opening the circuit when current exceeds safe levels, these devices safeguard against overheating and potential fire risks in electrical systems.
