I would connect the new subpanel to your main electrical panel. The reason
for this is if you have overloading problems in the future. Then you would
only need to upgrade your main panel/service to 200 amps and not mess with
either subpanel.

Why 100 amp instead of 60 amp in the barn you ask? Why not, besides I
already have a Square D 100 amp panel I bought that was much cheaper
than 60 amp panels I looked at, not to mention the expandability 100
amps offers. In the barn I plan to run lights, 20 amp power outlets,
an air compressor (220), small arch welder (220), gas furnace, and
typical power tools such as a table saw, drill press, etc...

Of course, if my "plans" aren't safe, than I would certainly change
whatever was needed to be considered safe. That's why I'm asking for
feedback from this group. In hind-sight, I really wish I would have
bought a new 200 amp panel when I remodeled the house. Ah...if only I
knew everything....lol

Thank you in advance, it's appreciated!

I agree completely. Install the new barn breaker in the main panel. Glad
to hear you going 4 wire.
If your careful you will not have a problem. Unless your trying to build an
project and your house is all electric. Which with an 100 amp service I will
bet you have some gas appliances.

Years ago I fed a residence (reasons are way to hard to explain) from a 60
amp 2 pole breaker. Unless the washer, dryer, oven were on every thing
worked fine until I changed it over to the utility some 2 years later. They
did trip 4-5 times those years but that is not bad. I owned a home in
Phoenix, 2 a/c's electric water heater, stove, and 3 swamp coolers. I
measured the conductors at the roof, pulling about 50 amps with everything
on.
