Findings (7)

R-SB-01Energised parts reachableImmediate dangerphotographic evidenceS5 × L3 = 15Critical

Live parts can be contacted without removing a cover or using a tool.

Action Restrict access to the board immediately and have an electrical worker restore the dead front before it is handed back.

Arc flash / electric shock · due 2026-03-28 · AS/NZS 3000 §1.5.4 · evidence VC-EXPOSED-CONDUCTOR

R-SB-02Blanking or gland plate missingNon-conformingphotographic evidenceS4 × L3 = 12High

An unused way or cutout is open, so the enclosure no longer provides its rated protection.

Action Fit correct blanks and gland plates. Do not use tape or sheet offcuts.

Arc flash / electric shock · due 2026-04-04 · IEC 61439-1 §8.4.2 · evidence VC-MISSING-BLANK

R-SB-03No arc-flash or shock-hazard labellingNon-conformingphotographic evidenceS3 × L4 = 12High

The board carries no hazard label, so a worker cannot select PPE from information at the equipment.

Action Calculate incident energy for the board and fit a label showing the boundary and PPE category.

Arc flash / electric shock · due 2026-04-27 · NFPA 70E §130.5(H) · evidence VC-NO-ARCFLASH-LABEL

R-SB-08Working space obstructed by stored materialNon-conformingphotographic evidenceS3 × L4 = 12High

Material is stored in the space a worker must occupy to operate or escape from the board.

Action Clear the zone, mark it on the floor, and give the displaced material a defined home.

Access, egress and emergency response impaired · due 2026-04-04 · AS/NZS 3000 §2.9.3 · evidence VC-OBSTRUCTED-ACCESS

R-SB-06Thermographic survey overdueRecords / traceabilityS2 × L4 = 8Moderate

No thermographic survey has been recorded within the interval.

Action Book the survey while the board is under representative load, and file the report against the board identifier.

Loss of design or inspection traceability · due 2026-05-27 · NETA MTS §9.15

R-SB-10Circuit schedule missing or out of dateRecords / traceabilityS2 × L4 = 8Moderate

The circuit schedule does not match the installed ways, so isolation cannot be planned from it.

Action Verify every way and reprint the schedule inside the door.

Loss of design or inspection traceability · due 2026-04-27 · AS/NZS 3000 §2.10

R-SB-15Main switch not identifiedRecords / traceabilityS2 × L4 = 8Moderate

The main switch is not labelled, delaying isolation in an emergency.

Action Label the main switch with what it isolates, in durable marking.

Access, egress and emergency response impaired · due 2026-04-27 · AS/NZS 3000 §2.3.2

Photographic record

Site photograph taken at assessment

An illustration of an LV distribution board / motor control centre with the outer door swung open (circuit schedule card on inner door), showing a 400A main switch, an exposed busbar chamber at top and three rows of moulded-case breakers behind an escutcheon.

Energised parts reachable — An open recess shows bare horizontal and vertical busbars with bolted joints, plus a red/orange conductor with an unterminated end at the right side of the bus chamber, all reachable with the door open.
Blanking plate or gland plate missing — Two breaker ways show dark open apertures in the escutcheon with no device or blanking plate fitted.
No arc-flash or shock-hazard label — Only a 'CIRCUIT SCHEDULE' card and a 'MAIN 400A' text marking are visible; no warning triangle, arc-flash or shock-hazard sticker anywhere on the visible faces.
Working space obstructed — Three cardboard boxes/cartons are stacked on the floor directly in the standing space in front of the board, one partly under the panel.
Housekeeping around the asset — Cardboard boxes stored on the floor around the asset; no spillage, water or loose debris otherwise visible.

Assisted by claude-opus-5; every observation adjudicated by the inspector before use.
