What likely caused the fire in the mini-refrigerator incident?

The most likely cause of the fire in the mini-refrigerator incident being attributed to flexible wiring revolves around how flexible wiring can wear down or become damaged over time due to movement and bending. Unlike rigid wiring, which is usually fixed in place and less prone to physical wear, flexible wiring can experience stress that may lead to frayed insulation or exposed conductors. This condition can result in short circuits or electrical arcing when the wires come into contact with each other or other conductive materials, potentially igniting a fire.

Additionally, flexible wiring is often used in appliances where components must be moved or adjusted, which increases the risk of damage. Proper maintenance and inspection protocols are crucial to identify potential hazards associated with flexible wiring, thereby preventing such electrical incidents. This explanation emphasizes the specific risks associated with flexible wiring in comparison to other types, such as insulated or rigid wiring.
