"We found that the initial underway blackout was caused by a series of electrical-related events that began when a signal wire (Wire 1), one of many in the main switchboard, electrically disconnected from its terminal block. The terminal block, a small, insulated plastic block, connected Wire 1 to another wire within the vessel’s high-voltage switchboard. When Wire 1 electrically disconnected, one of the high-voltage breakers connecting the high-voltage bus to its step-down transformer— a mechanism that lowered voltage carried from the main, high-voltage, electrical bus before transferring it to the low-voltage bus—opened.
Installed on each signal wire were labeling bands (wire-label banding), which were small silicone sheaths made of thermoplastic material that was heat-shrunk around the wire and had its associated terminal block printed on it. We found that Wire 1’s label band (wire-label banding) covered all of the ferrule’s blue insulated collar, increasing the ferrule’s overall circumference, preventing the wire from being fully inserted into its terminal block—leaving Wire 1 vulnerable to becoming electrically disconnected. We found that if infrared thermal imaging, an inspection technique that allows inspectors to identify possible points of failure in electrical components not visible to the human eye, had been used to inspect the Dali’s high-voltage switchboard connections as part of the vessel’s preventative maintenance program, the loose Wire 1 may have been identified."

/kkā tā, sākotnējs test nez vai atrastu problēmu, jo kontakts bija, bet par kārtu rūpīgāka ikgadēja pārbaude, iespējams, varēja noķert problēmu pirms avārijas.
