I need to correct safety problems in a wiring gutter. Rats gnawed (SP?) the insulation from a portion of a 2/0 hot cable at the point of passage just barely above an insulated conduit bushing.

I believe that there is enough slack to raise the cable above the bushing and apply some sort of fluid insulating product.
Cannot tape cable as it touches two others entering the conduit. Could gently separate cables from each other to apply a liquid or paste type product all the way around the damaged cable.

Would appreciate advice on products to renew the original
insulating qualities over the bare area which is about one inch long and not quite half way around the wire.

Thanks and appreciation,

Never thought of a cold shrink sleeve. Very possible to disconnect from main feeder (500CM w/split-bolt) and slip a sleeve on when some other needed work is done.

Only involves about one foot of #2/0.

Hope the electrician does what I do for split bolts. Plastic tape ,Mastic pad ,plastic tape again. Razor knife will split it in half and easily peel off. I should add a layer of friction tape in there for physical protection as I have seen even these blow out on rare occasion.

Thats what I do to non-insulated connections, but the first layer of tape is sticky side out.

Yep, backwrapping is our friend!

If I have the time, my favorite method is 1) Backwrap with 33. 2) Coat with liquid electrical tape and let dry. Two coats if you have time. 3) Wrap with friction tape. 4) Wrap with 33.

When it comes time to open the splice, the first layer will easily peel away and you will find a perfect connection inside, even after years of outdoor use.

There is a product that plumbers use called 'stretch and seal' tape. I use it for antenna connections. GREAT stuff, but no UL listing. I am sure it could be used in place of the liquid tape with no problem at all. I have used it for years on coax connections and it does what it says it does.
