NOTE: ALL 12VHPWR cables can fail
Potential Causes:
1) FOD (Foreign Object Debris)
- Caused by manufacturing error
- Caused by Design Oversight (Dimples to pin contact)
- The debris could've already been in there
- The debris could've come from the end user
- e.g. Nickel/Tin plating from the connector can get scrapped off over time via repeated insertions due to bad plating process.
The exposed Copper could oxidize and cause high resistance
2) Heat generated through a parallel high resistance conductive path
- Caused by FOD
- Caused by EXTREMELY BAD User Error in combination with a taught wire
e.g. Inserted only (4 - 4½)mm out of 6½ mm of Plug Teeth exposed/Un-Socketed & sharply bent to one side
Any Burrs or debris caused by bad connection, it can lead to increased Resistance, causing heating
- It may take substantially more time for the slightly improper connection to cause melting / failure
- A TRULY bad connection will only take minutes for the melting / failure to occur
Steve from GN claim's it's not a Adapter design issue:
- Fool's errand, waste of time to go down that path
- You should feel comfortable using the 12VHPWR in general, but...
It requires you to seat the cable properly, fully, (Hearing the click of the locking tab)
There should be no gap between the plug base and the receptacle where you can see the Plug teeth
- Avoid pulling the cable taught
