Can overhead service wire be run inside conduit?

[Alternety]

I have read through this thread a couple of times and I am thinking things got off track part way through. In the fourth post, leejosepho describes the wire. It is a single stranded wire i.e., one #6 wire). It does not appear to be SER or multiconductor. It is copper. His garage is attached so it is not hanging over a span. It is rated THWN-2 which I think means it is ok for underground conduit (although there is no indication that the proposed use includes this) and use to 90*. It would think it ought to be in conduit because as he wants to use it it is simply 4 THWN single wires. Certainly for protection if it is exposed.

Does this make sense?

Yes, I probably confused things by asking about a second kind of wire in a thread originally asking about overhead service wire.

My garage and workshop are attached to the house, so I need to run four wires to a panel that will not be bonded. My boss has a piece of twisted service wire I could use, but that would have to be in conduit and I would have to add an insulated neutral since the ground (service neutral) is already bare.

To be more practical, the second piece of wire I have mentioned is #6 AWG, and it could be run as four strands in conduit as long as the ends are color-coded (black/black/white/green). But, maybe the SER wire Chris has mentioned can be run through walls without conduit?

Why dont you just go buy some 2/3 SER cable? good for 90 amps ...

You got me to thinking there, and I have decided to just go ahead and get whatever I need to replace my existing main (100-amp) panel with a 200-amp panel, and to then move the 100-amp panel to the workshop as a sub. I will let you know what wire the guys at the supply house recommend ...

Thank you.
