For equivalent wire gauge would you just compare the center conductor
diameter to a wire gauge chart?

It is pretty easy to insert and remove power from a coax that also has
RF on it too. Just a choke coil and capacitor at both ends. If you
want details give me the frequency and what kind of power and I will
design it for you.

Yep .we used. LMR 400 to power custom made receive amps for WMux
radios we modified long time ago.

Just make sure if you hook it up to 120 VAC main current you don’t
put the hot wire on the outer conductor of the coax...

You can run DC /or/ AC over it.
Think of it this way, 1000 watt ham radio puts 223 volts AC
(at RF frequencies) on the coax and everything is just fine.
All CATV systems put 60 or 90 volts AC on the line to power
the amps.

Any reason I couldn't use 1/4" heliax I already have in place
up a tower to run power to a POE switch?
This is the stuff:
