Actually, the plan is to put the old 3/4 inch conduit into the junction
box with a straight-through connector.
Then, coming out of the junction box, will be half-inch conduit that goes
to the motors, with a straight through half inch connector on the end
that screws into the motor body.
My only problem right now is figuring out why the 3/4 inch conduit
doesn't fit into the 3/4 inch holes of the box. It makes no sense unless
I'm assuming something that isn't the case (which it must be).

I'm not sure what we're looking at in the pic. On the left,
is there a bushing inside that conduit? That's what it looks
like to me, a 3/4 conduit with a bushing inside. And what are
you showing the end of on the right? The old fitting that
went over the conduit on the left? If so, then what that appears
to me is some different kind of liquidtight fitting that uses
a seperate bushing inside the conduit and then the fitting itself goes
over the conduit.

I'm not sure what the yellow thing is but here is a side view:
It turns out that, with experience, the whole thing turns out to be
comprised of half-inch fittings!
1. The half-inch conduit ...
2. ... had a half-inch nut ...
3. ... which held a half-inch elbow ...
4. ... which was screwed into a half-inch hole in the motor!
Note: The plastic nut, plastic elbow, and gray conduit are all one inch
in diameter; but they're still considered half inch equipment, apparently.
Ahah! I knew something wasn't right with the end of that
conduit we were looking at. It's as I suspected, there was
a bushing inside it. The inside hole diameter was too
small, the wall way to thick for it to be liquidtight conduit.
NEMA 3R equipment is weather resistant but not really water tight.
The boxes will accumulate water if the rain hits them directly,
particularly after the gaskets start to degrade.
A lot of guys will drill a small hole at the lowest part to allow
water to drain out.
That is why anything outside or underground is called a wet location.
No. Just that the picture that you showed us of the end of the
conduit did not look like liquidtight conduit of any size.
The hole was small, the wall was way to thick. That's
why I said it looks like it has a bushing in it, which was
You have a piece of 3/4" nonmetallic flex. It looks like you have a 1/2"
X 90 degree NM flex connector. You need a 3/4" NM flex connector. The
larger threaded side of the connector is not pipe threads. it only
threads onto the tightening nut that goes on the NM flex. If you want to
install the 3/4" into the box with 1" openings, you'll need a 1" x 3/4"
Also, I would use a box twice that size. You have 6 wires
entering the box, which is probably close to the limit for
that box. It's also being put in to allow easy disconnect of
the motor, so having some extra room is a good thing.
And a larger box would allow for the addition of another
wire if you decide to go to a dual speed pump at some point.

It's the biggest box they had.
I really wanted three holes in each side (one for each motor).
A lesson learned is that the only thing this pipe cutter turned out to be
good for was for cutting the conduit (but a smaller irrigation cutter
would have worked even better):
Unlike the useless pipe cutter though, the wire strippers and the wire
crimper seemed to do the job quite nicely:
In fact, they did so well, I'm wondering if it would be to code to mate
the female spade connectors to male spade connectors instead of cutting
off the ends to wire nut them?
*You are confusing trade sizes with actual dimensions of the conduit. Your
flex has some writing on the outside of it which should include the trade
I have put together a chart of the actual dimensions of some conduits,
however it does not have the flexible type that you have listed yet. The
other conduit dimensions may give you an idea of what size you really need.

The old cable clearly says it's 1/2 inch cable on it, had I only looked!
In hindsight, I was lulled into complacency because I could easily
measure the fat end of the original elbow at an exact 1 inch, so, it
seemed so natural that the conduit was one inch that I didn't doublecheck.
It was only when the one inch box didn't fit, and the 3/4 inch box didn't
fit either, that I took a second look at the problem.
Even then, it's wholly unnatural that both sides of that elbow were
actually 1/2 inch connectors!
