    I did this at my parents' house; I sleep just fine knowing how I did this splice.

    T&B makes a line of C-Taps that are listed as Grounding and Bonding Equipment (suitable for splicing the GEC) that can be applied by T&B lever action crimpers. The T&B C-Tap #54720 will do two #6 solid copper conductors side-by-side. The #54720 is color coded "brown". The installation instructions are available Here.

    I picked up the tool, used, on eBay.

    I know about the irreversable crimp option offered by NEC. But are the splices listed for SOLID conductor?

    ETA: just checked their site. Burndy YC4C6 are good for solid as well.

    We use Ilsco C-Crimps that are listed for Solid CU.

    The T&B C-taps are listed for solid.

    Thank you.
    Copper is malleable so I guess it can be crimped. Even at #6AWG or around 16mm2 would be closest for us in the SI world........
    Not something I've tried...........

    Could that be carrying neutral current thru water pipes?
    Caused by open service neutral?

    I thought that looked funny but didn't blow it up to look at it further. I figured he HAD to have known about it, and didn't share, so it must have been a non-issue. But, well, it sure LOOKS LIKE an issue!

    Looks like a metal raceway enclosing an GEC that was not properly bonded to it at either end. Perhaps a shot of lightning at some time or another, proving a picture is worth a thousand words.

    Personally, I would not bother with putting that type of splice in a box nor would it V.
