I've got a detached garage 60' from the house snd going to feed it overhead with Quadplex wire. I'm install 120/240v single phase 60amp to a sub panel in the garage. I've built a riser (rigid) on the open gable side of the garage. Now, here's the question..... on the house gable up high, I've got a 6/3 romex feeding through the attic and stubbed out. It's in a 3R J-box 2' from the point of the gable (highest point of the house) so I can easily get my driveway height. What is the easiest way to splice the quadplex wire to my romex sticking out? They don't necessarily make a quadplex connector.

You might have an issue with that romex hanging out in the air. I don't think it's rated for that.

As far as splicing, a WP Polaris? I'm envisioning a flying splice like utility companies would make to your service riser.
 
Do you have any photos? Is the riser also in the 3R box? What's at the end of the rigid conduit?

I took it as the riser was at the out building to take power down to his panel and the 3r box was on the house (with the romex in it).

I ASSUMED (lol) there would be a weatherhead on top of the riser on the out building and connections made like an overhead service drop.

Can you install a weatherhead on the top side of the 3R box and loop the quadplex conductors individually into the weatherhead? (Don't forget the drip loop or your jb will get messed up).

I thought about that, just a short piece of conduit with a weather head to where I'm not going through the roof. Just didn't know if that was code or the inspector will like it.

That wold work or if you didn't want the box on the outside then an LB conduit body through the wall and a box on the inside where you can make your transition. The NM cable conductors cannot be on the outside in a raceway.
 
It's a feeder so prohibitions against running it through the structure don't apply. I would install it exactly like any overhead service except that you can run SER from your sub panel right out to the drop where you would put a weather head on the end of the SER, form your drip loops and splice.

That said, I can't picture how you have the conduit and splice box. You can't run Romex outside. Pictures would be nice.
