Field note (open supply query): 70mm mains in down to 25-35mm tee off or dedicated? — resolve looped-vs-dedicated feed arrangement on the F-series 50 mm mains before finalising the outgoing design.
4. Condition assessment
Scored per the Condition Scoring & Rating Model (six standards-referenced dimensions, 0–4 on the P-scale). Rating is gated — a single safety/structural P2 breach sets RED regardless of the averaged Index.
| Dimension | Score | Grade | Observation |
|---|---|---|---|
| Electrical safety & compliance | 2 | Moderate (P3) | Direct-contact / earthing / labelling integrity |
| Structural & enclosure integrity | 0 | None observed | None observed |
| Corrosion & protective coating | 2 | Moderate (P3) | Corrosion of fixings, bars and coatings; general fouling |
| Ingress protection | 2 | Moderate (P3) | Sealing of penetrations against dust / water ingress |
| Access & working space | 3 | Major / safety (P2) | Door opening arc and working-space clearance |
| Thermal / fire & component | 0 | None observed | None observed |
Rationale. The gated rating is RED, driven by a non-compliant door / working-space clearance (AS/NZS 3000 Cl 2.10), corrosion to fixings and bars and unsealed penetrations / ingress (Condition Index 38.8/100). RED reflects a gate breach — a safety/structural P2 or an AS/NZS 3000 Cl 2.10 clearance non-compliance — that cannot be averaged away.
5. Defects
Field-observed defect(s) for this board, itemised into discrete findings — each with its own priority and category.
| Ref | Category | Defect | Pri |
|---|---|---|---|
| D-01 | Clearance | Non-compliant door / working-space clearance | P2 |
| D-02 | Housekeeping | Internal dust / dirt accumulation | P4 |
| D-03 | Ingress | Unsealed cable penetrations at base / gland plate | P3 |
| D-04 | Corrosion | Significant rust / corrosion to enclosure, fixings and bars | P3 |
| D-05 | Electrical | Cabling arrangement / condition concern | P3 |
6. Suitability for the LED works
Suitability for LED worksYES
The new LED floodlight load and driver footprint are materially smaller than the legacy HID gear removed, and the existing 3-phase supply, 35 mm² feed and cabinet isolation are adequate for the new works. This conclusion is universal across the fleet and is independent of condition.
