As For testing HV Gloves I've Heard to Blow them up with air Using you breath, Then to roll the cuff up to see if it leaks. Never tried it though. I Generally try HARD not to Work on Live Stuff that requires Gloves.
As for Taping Split Bolt Lugs. We Start with a Lap of 33+ Then SEVERAL wraps of 130C, Then Cover it in 33+ Just to Protect the 130C. The First Wrap of 33+ that you put on is to aid you when you remove it next time. I'll asume that you have removed at least one splice that had 130C right on the lug. Pain it the You know what to get off. That first wrap 0f 33+ saves alot of time and Cussing when you remove it! As far as removal. Use a razor knife to Make a ring around it, Clear to the lug/splitbolt. Then use a needle nose pliers to pull the two sides apart.
