- Resources: Quality & Evidence · Spec Definitions
Top failure modes (what usually goes wrong)
- Surge damage: SPD level not specified or not installed correctly.
- Sealing/IP failures: water ingress at cable entries and junction points.
- Corrosion: wrong protection system for coastal/industrial environments.
- Commissioning gaps: aiming not verified, protections not recorded, no acceptance records.
- Silent substitutions: components changed without approval; no traceability.
Evidence gates (pass/fail)
- Photometrics pack (IES/LDT + simulation outputs)
- Surge protection spec + evidence
- Sealing/IP evidence + inspection records
- Corrosion protection requirement + records
- Commissioning checklist + acceptance records
