There will almost certainly be that unknown and unmarked cable, that seems to not be used - but turns out, after being cut, to have been critical to operations.

Then there will be those that are ad hoc power cables - use of a Fluke (or equivalent) power-sensing wand is a prudent step to take before cutting the cable.

@karlauerbach we’re cutting as little as we can for exactly that reason, and nothing that we can’t find at least one disconnected end on (ie. no flowing electrons)

@WiteWulf On the Interop show network we have had to clear our shownet wire out of Las Vegas casino spaces - that's scary, but not for technical reasons - it's that the casinos are quite protective of their networks and we didn't want to be visited by Guido From Baltimore.

I've encountered a seemingly disconnected end, such as when a wire is being used as an antenna, but that's rare. Sometimes there are microphones , fire sensors, or other sensors down there.

A lot of people do not know that many cables are factory marked every few feet with distance numbers and other identifiers that make it a tad easier to figure out which cable is which.

Some really old cable types have a layer of grease under the outer layer of insulation. Yeech.)
