Domestic and industrial wiring
Lighting and fan connections
Internal wiring of control panels
Connection of small motors and machines
Appliances and portable equipment
Cable not powering device – Check continuity using a multimeter.
Overheating of cable – Possible overload; verify current rating.
Burn marks on sheath – May indicate a short circuit.
Cable is stiff/hard – Indicates aging or exposure to heat/oil.
Frequent tripping – Check insulation resistance for leakage.
Uneven power supply – Confirm proper connection of all 3 cores.
Color fading of insulation – Could be UV exposure; consider a UV-resistant variant.
Loose connections – Tighten terminals and check for damaged strands.
Frayed wire ends – Re-strip and terminate using ferrules.
Low voltage at end point – Measure and assess voltage drop over cable length.
Vibration at joints – Use vibration-resistant glands.
Mechanical damage – Inspect for cuts, nicks, or rodent damage.
Moisture entry in sheath – Use waterproof glands and joints.
Noise in connected motor – Check for electromagnetic interference.
Short circuit signs – Use insulation resistance testing.
Discoloration of copper – Sign of oxidation; may need replacement.
Blown fuse – Check cable load rating against fuse rating.
Hot plug point – Verify contact resistance and terminal tightening.
Rusted terminals – Clean or replace to avoid poor connectivity.
Cracks on insulation – Replace cable if aged or exposed to harsh environment.
Cable sagging – Proper clamping or conduit is needed.
Unequal current flow – Inspect if all 3 cores are functional.
Buzzing sound – EMI interference; ensure proper grounding.
Breaker trips under load – May be undersized cable for the application.
Improper earthing – Ensure grounding conductor is correctly connected.
No continuity in one core – Test with a continuity tester and rejoin if needed.
Intermittent failure – May be internal strand break; replace.
Flickering lights – Voltage drop due to long cable runs.
Connector heating up – Improper crimping or loose lug.
Incorrect phase sequence – Recheck phase assignments at both ends.
