Exactly. If you think you may need a larger feed for future, you could pull
the number 8's as I describe, which will give you 40 amps, but you'd need a
panel and the ground rods. If the two 20 amp circuits will suffice, four
#12's will get you there. If you can pull out one of the existing romex's,
you could tie the new conductors to the other and use it as a snake

if it's "still" legal to not run a ground with the circuit conductors,

if he does that, nothing conductive can go between the buildings,

catv, telephone, metal water line, etc.

As others have noted, I'll reiterate the more significant problems
here -- first, for underground even in conduit you need wet-location-
rated conductor and what you've described isn't -- you need an UF and
could dispense w/ the conduit except for protecting it going
underground. 3/4" conduit as you noted later isn't really large
enough.

I strongly recommend going to #10 for the feed and installing a small
subpanel. It will be far better in the end to spend a few extra bucks
up front. But, in particularl, the interior romex is _NOT_SUITABLE_
for the application.

You could stuff four #8 THWN-2 wires in there pretty easily, and #8 is
easy to work with. That would give you a 40A service with a separate
ground. Or run 2 black sixes and a white #8 for a 50A (60A? I don't
remember) service and establish a new ground at the garage. Either of
these would be legal with 3/4" conduit.

Your starting to lose me here (noting conductive can go between th
buildings...)

In the same trench (outside of the conduit) I ran a coax line. Not
sure if this impacts things or not.

Correct me if I'm wrong but it sounds like it would be acceptable (and
simpliest) to pull out the romex and push 4 #12 THWN conductors
through (black, red, white, ??). (Is #12 easy to push or will I need
to fish it through?) This would give me 2 120V 20 amp supply lines,
one common neutral and a common ground. Without adding a subpanel I
could splice these into romex in the garage. But as recommended it
would be better to push #10 or #8 to increase the amperage and add a
subpanel in the garage.
