Re: [TCML] Consensus on HV cable
David
Check once again for correct acronym EPDM (ethylene propylene diene monomer) or
EPR (Ethylene-Propylene Rubber) non shielded jumpers. MV power cable looks like
below...

Transformer primary connection jumper wires would last FOREVER in Tesla Service,
but expensive at ~$6.00 per foot. But #2, 15kV labeled cable would
have a undeniable WOW
aspect as well.
