What type of wiring was determined to be the cause of the fire linked to the mini-refrigerator?

Flexible wiring was determined to be the cause of the fire linked to the mini-refrigerator primarily due to its nature and typical application in household appliances. Flexible wiring is often used in devices that require movement or need to be easily repositioned, which can lead to wear and tear over time. This wear can create potential hazards such as short circuits or electrical arcing, especially if the wiring insulation is compromised.

In the context of a mini-refrigerator, where the wiring is consistently moved or bent during use, the risk of damage increases. This type of wiring may also be less robust compared to rigid or high-voltage wiring, making it more susceptible to overheating and electrical faults when subjected to continuous operation—especially in an environment where objects may be placed against or near the wiring.

Understanding the types of wiring is crucial for identifying potential hazards in healthcare settings or any environment where electrical appliances are used, emphasizing the importance of regular inspections and maintenance to prevent fires related to electrical faults.
