Feeder loading
(OP)
Dear colleagues,
We need to connect a 800 kVA transformer (480/480)to user grid. The available single busplug is sized for approximately a half of transformer FLA. Is it possible and/or legal to use 2 busplugs to feed a transformer via 2 parallel branches (assuming their equal length)?

Article 240: "Fuses and circuit breakers shall be permitted to be connected in parallel where they are factory assembled in parallel and listed as a unit. Individual fuses, circuit breakers or combinations thereof shall not otherwise be connected in parallel."
