Frayed insulation on POCO connection


Hi all. Sorry for the double-dip on the non-DIY questions. After I put up our Christmas lights, my wife noticed that the insulation on the wires on our side of the POCO connection is frayed before it enters the conduit to the basement. The conduit goes up from the basement on the outside of the house, through the roof, and up a few feet further. Our electrician is coming tomorrow morning, but I wanted to know what the experts here have to say. I expect the wires will have to be replaced, but I want to know what to expect beyond that.

The pictures aren't very good, and I wasn't close enough to get a good look anyway. It looked to me like there were two layers of insulation and the outer was frayed, but I don't know about these things and, like I said, I couldn't really get a good look. The fraying on the insulation one of the hot wires (the uninsulated wire from the POCO is neutral and the other two are hot, correct?) is worst near the top where it enters the conduit, but it's hard to see that in the pictures.

Thanks in advance!

If it's just the outer coating you should be fine. The outer is just the gas and oil resistant coating.

Yep, that's the nylon outer covering. It also makes pulling the wire through conduit easier.

The outer covering is not sunlight resistant, so it'll chaff off over time if installed outdoors. The actual insulation under it is sunlight resistant, and it'll stand the test of time.

Thanks, folks. I appreciate the quick replies. Do you think the wire should be replaced? The outer layer is there for a good reason, I'd bet, but I'll see what our electrician says tomorrow. Thanks, again!
