Service drop scraping

Recommended Posts

This service drop is pulled across the rake edge. This is a house near me that I told the utility company about over a year ago and they had someone come by and say it was ok. Isn't it just a matter of time before the insulation gets scrapped off the conductors and it shorts out?

It sure is, unless the insulation is already brittle and crumbling off, then you'd only need contact with a conductive material like rake flashing to get a fiery electrical flash. Only the utility fuse protects it and it's a big one, a super lag. It can vaporize quite a bit of metal before it's over.

Worse than that, if it wears through the roof edge, even without cutting through the insulation, they could end up with a roof leak and property damage.

The utility company could just snap a sheath over the cable to protect it.

On the other hand, the service drop really shouldn't be supported by a piece of trim.

I've seen these totally worn through with bare metal rubbing on the shingles.

I'm not advocating that's good, but it doesn't necessarily mean it all shorts and blows immediately; it'll hang around for the big surprise when all the factors line up.

I'd put a sheath on it; if the power company says it "OK", they're not going to restring the drop, and the owner isn't going to install a new service riser.

Thanks for the replies.

Wouldn't a worn conductor plus some rain make it short to the neutral?

No. It wouldn't be enough current flow to blow the fuse.

Nah, Bain, I just flipped it to upload here. I chose to use the first one in the report instead of the last one, but flipped that last one before I uploaded it here.

I at least have my makeup on before being photographed.

Uh, not that I make it a point to look for such things, but where is Mr. Pink's yingyang?
