Wrenches,
I would like to concur with Mike from MDElectricSolar. My rooftop junctions always use Buchanan copper sleeves crimped with the Buchanan C-24 crimp pliers. After twisting the stripped ends together to a length exceeding the sleeve length I apply No-Ox-ID A Special grease to the twist prior to sliding on the sleeve. Then crimp the sleeve with the C-24 pliers which drives the grease into the wire strands. Trim the wire strands at the end of the sleeve and then snap on the insulating cap. I have confidence in this joint. Crimp sleeves are now made by Ideal and the C-24 pliers can be found on eBay.
