Which TRU does the ADG power?

Explanation:
The ADG is powered by the highest-priority, dedicated essential power source to ensure uninterrupted operation of a critical load. Essential TRU 1 is designated as the primary feed for that essential bus, so it powers the ADG under normal conditions. The other TRUs exist to back up or power other loads, and they normally stay separate from the ADG’s feed to avoid fighting sources on the same bus. In normal operation, only the primary TRU feeds the ADG, with backups coming into play only if the primary fails or during specific transfer scenarios. That’s why Essential TRU 1 is the correct choice.
