The DWGs didn’t spec bare. I had the #2 in stock. The ground ring that I had to repair was bare 2/0 solid. I couldn’t find the 75’ I needed to repair it (excavator dug it up) so I used 2/0 bare copper.

This trick is particularly useful if you encounter old 7-strand ground wire that doesn't quite fit the hole in the mold.


If the sides are getting worn out wouldn’t the inside area be wearing out too?

The sides seem to wear out faster. The molds are relatively soft, I think every time you clamp a wire or adjust the position of the mold once it is clamped onto the wire, a small bit of abrasion takes place. Once a leak happens, it seems to accelerate the wear many times over. I dunno, I even do it on new molds. Seems like good prevention for a few ¢ worth of duct-seal.

It’s actually the moisture that does it. Once it is up to temperature you will have fewer problems. Heating it up with a torch is not optional.

It is. You have to keep the torch on it for a while. You can actually take what appears to be a dry, cold mold, start heating it with the torch and you can see the moisture start to come out of the mold where you first apply the torch. I then chase the moisture to the far end of the mold and viola, dry mold.

No splattering on the first weld which is the indication of moisture.
