Redundant power supplies don't necessarily make critical infrastructure resilient. Shared transfer switches, control circuits, physical pathways, and maintenance procedures can create single points of failure even when multiple power sources are available. Through a hypothetical 700-kW facility, the article demonstrates how a failed transfer controller can interrupt service despite adequate backup capacity. It outlines a practical method for identifying hidden dependencies across electrical capacity, protection, controls, physical infrastructure, and human operations.
