Here on Long Island, quite a few homes have
excessive humidity build-up of moisture on the water main pipe that enters the home.
What I normally do during a service change
is to Scotch-Kote the clamp and surrounding
area of the pipe. Too many times have I seen
the clamps severly corrorded. With the scotch-kote on the corrorsion stops, and years later you can check the clamp like it was new. I would like to see this as part of the code, but I think the breathing of the fumes of the Scotch-kote might be an issue. Any ideas?

a similar idea i have used with split-bolt connections is to wrap them in a layer of dux seal before tapping them up.
the same theory applied....

Steve,

Welcome back!

I was thinking maybe clear lacquer.

Don't they scotch-kote furniture? I can't see how it could be that harmful (except maybe while spraying?) If you know the chemicals involved or a specific brand you can look up the MSDS info.

That would be scotch-guard...

Scotch Kote is an "electrical" sealer... Don't get it on your skin!

There seems to be quite a few different types.

If you go to the following page and enter "Scotch Kote" where it says Trade Name it will bring up a list of MSDS for the different types.

To the best of my knowledge, oxides of copper are still excellant conductors, unlike aluminum oxide which is more of an insulator. If I was to pick a product to use, it would be "Copper Kote" by T&B, applied between the clamp & pipe.

WOW!

I never realized there were so many different types!

I'm going to look at a bottle at BGE tomorrow to see which type I usually buy when needed.

BTW the ScotchKote I use tends to weaken the jackets of SOW cable. Learned that one the hard way in a fountain light installation. (no one was hurt). I hardly have used it since then. My buddy (and fellow EC) Joe M. got some on his exposed (river shoes) foot (don't tell OSHA) and had an ulcer for about a month on the top of his foot. Nasty! (In his defense, he had to wade out in 1.5' of water to make the repair) I have used it to WP submersible pump connections since, however. The remainder of that bottle ended up as a 1/8" deep mess in the back of my truck... Got the lid on crooked... Remnants remain on some of my tools...

Uhhh.. So much for coherence!

I've found that ScotchKote may not be compatible with other brands of tape. Best if you apply it over other 3M products. When it works, it does a great job, when it doesn't it makes a mess.
