Not sure what you mean by "jacket". The plastic was still surrounding the wires they routed inside the conduit. But these plastic-coated wires were always inside some sort of metal conduit, never just run inside a stud cavity behind drywall.That is how my main breaker box outside is passed into the backup panel, back knockout on both boxes as they exist on the boxes with a 3", I think as it is large dia. short conduit. Passed.
By exposed cable do you mean without it's jacket? My 100A cables are in wall cavity in its jacket.
