Silght apprehension yesterday (Friday) installing a replacement D-50 Expansion Module because it was used. Made sure my work order in writting said so. It’s the unit 3rd from left. This switch board controls what feed powers vault-3 (west 1/4 of runways/taxiways and related equipment). Two house powers and one generator with closed transitioning. Supposely getting new parts from different vendor through different requisiting that takes much longer. The oringal problem was the generator start contacts didn’t always make up. It was somewhat imbarassing how we (2 others and I) figured it out. Apparently the “D-50s” are no longer being made?
