Proper way to terminate overhead wiring at weather head feeding a detached garage


I have a detached garage that is fed with a 30amp 240V 2-pole circuit using #10 wire attached to a steel messenger cable. However, I think the way the overhead wires are connected at the weatherhead is ugly (see picture).

Is this even code-complient, and is there a more "aesthetically pleasing" way
these wires can be connected?

Thanks for any suggestions.

Looks fine from this vantage point. But who knows what the connection is, if its covered in tape.

The wires are in this position to allow water to drip away from the conduit and structure.

This is called a drip loop. Not the best of jobs as I would have made an actual loop.
I see zero issue other than a better drip loop and would like to know what is connecting those wires under the tape.

Looks like wire nuts taped up.

Some simple butt splices would work, just keep them from being in the bottom of your drip loop.

carmusic: The picture was taken with a zoom lens, so it flattens the image a bit, but there are 4 separate wires running from the breaker in the main panel all the way to the garage (ground, neutral, 2 hots). They are feeding a subpanel, and the neutral is kept isolated from ground in the panel.

wirenut1110: yes, that is right, those are wirenuts with some tape on top. They do appear to be gel-filled. I guess a butt-splice would look a little nicer (IMO). I wasn't sure if those were code though (I know they are very common on 12V car electrical systems).

On a related question, if you look at the picture full size, you can see how the clear plastic coating is deteriorating on the wires, but the colored insulation seems to be fine. Is this normal, or was the wrong type of wire used?

Well, since you asked, I doubt, very seriously, that individual conductors were ever allowed to be secured to a messenger like that.

But hey, I've been wrong before. Seems to me those wires don't have any sunlight resistivity.

It's there and it looks like it's been there for a while so, I wouldn't worry about it.

I wouldn't know what the code was when that was installed.

The smallest messenger supported cable you can get, from what I've seen, is a #6 quadraplex code name Chola.
