Test set up with an overhead line to a 20 Amp MCB protected piece of 1.5 mm² TPS cable.
Later the MCB was bypassed to see what happened.
The 1.5mm² TPS overheated rapidly and burnt out.
A bolted short was made on the OH line.
The overhead line 2.5mm² overheated rapidly and the pvc insulation melted as well as the line sagged.
At the end of the video an other piece of 1.5mm² TPS cable was used again.
