e.g. 1CA1, 1FP1, ADIRU, DEU-B
REFERENCE ONLY — not authorized for maintenance, repair or return-to-service. The deactivation step of the maintenance task decides which breakers to open, safety and tag; this page does not. A FIN is linked to the breakers that carry the same two circuit letters (1CA1 and 10CA1 are both CA) and, where both give one, the same side; only the ones whose name also names the item are listed. Only 585 breakers carry a panel and grid position, so a FIN with none here may still have one.
