Standards Myths on Projects
Avoid checkbox compliance that still leaves equipment exposed.
Myth: any CE-marked SPD is equal
Performance values differ widely. Compare Up, Iimp/In, and TOV behavior for your system.
Myth: standards replace engineering
Standards set frameworks. Cable lengths, board geometry, and load criticality still need engineering judgment.
Myth: paper risk study without installation QA
A perfect report with long SPD leads and missing bonds will still fail in the first major storm.
