Repair jacket on Service cable?

[gb99]

Hi:

An errant drill bit rubbed against the outer jacket of the SE cable going into my new 100amp sub panel. I want to stress the cable was rubbed against, not drilled straight into.

The hole is less than the size of a pencil eraser. It is a 2 awg cable with a grey outer jacket, webbed translucent layer, and then 4 insulated conductors. The insulation on one of the conductors was very slightly rubbed - just barely touched - the conductor is still fully insulated with no metal showing. None of the other insulation was touched.

Electrical inspection was just passed. Can this jacket be repaired in a way that will make the cable 100% safe for years to come? The problem area is in the vertical run of wire in the stud bay, directly beneath the panel. My research identified people using 3m 33, 88, 2228 etc.

I can skip the wall insulation in that stud bay (interior garage wall) if that makes it safer.

Do the conductors get hot where this might ever cause a problem?

Thanks!

As long as the insulation on the individual wires is still good I think you should be fine, you can wrap it up with some super 88 if you want, I wouldn't bother with the mastic though. No, they shouldn't get hot....if they are getting hot you've got bigger problems to worry about.

Take a pic so we can see what we're looking at.

GJ consensus will have you running new cable back to the power plant. In reality, if there’s no metal showing, a couple wraps of electrical tape should be fine.

Super 33 should solve that problem,I'll wait in the corner for the firing squad.

Couple dabs of liquid tape.

Not likely good enough for this crowd, may need to upsize to at least 4/0 copper and also rewire all of your closest neighbours' homes just to be safe...
