Common issues

• Insulation resistance degradation from moisture ingress at glands or terminations
• Sheath abrasion or chafe at cable transits and bends
• UV degradation of outer sheath on exposed deck runs
• Armor corrosion in wet, salt-laden spaces
• Overheating or insulation breakdown from overloading or poor derating in bundled runs
• Termination lug looseness causing localized hot spots

Inspection checklist

• Insulation resistance (megger) test at scheduled intervals
• Visual inspection of cable runs for chafe, mechanical damage, or sheath cracking
• Gland and penetration seal condition check (watertight/gastight integrity)
• Cable support and cleating condition check - no sagging or chafe
• Termination and lug tightness check, thermal imaging where practical
• Armor continuity and earthing check

Service intervals

Typical wear limits

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

• Cable by type and size, cut to length as needed (no fixed part number)
• Cable glands and penetration seals
• Termination lugs/ferrules

Safety

• Fire-spread risk if the wrong cable type is substituted for a fire-rated circuit - never substitute types by space classification
• Electric shock hazard from damaged insulation - isolate before working on a run
• Armor must be properly earthed to avoid stray currents and shock hazard

Class survey

Class checks that the installed cable's type approval (TAE00004K5) matches installation drawings, that fire-rated (FR/FRA) types are used in required spaces such as essential and emergency circuits, and reviews insulation resistance test records at periodic survey.
