Lightning protection candidates often miss that bonding resistance thresholds differ dramatically between structural steel and buried pipelines. The NM ES-2 exam punishes applicants who memorize NFPA 780 tables without grasping *why* specific grounding electrode configurations fail under transient surge conditionsโa distinction that separates passing scores from advanced competency.
