[RE-wrenches] Split bolts

We've found that Scotch 88 tape is much less prone to heat sag and thicker so much more appropriate in containing the mastic.

The points on the legs of the split bolt are sharp and the mastic and tape had crept away from this point and exposed a tiny point of metal.  This point would have contacted the dead front lightly or at least would have been in close proximity.  Had I energized the breaker, I would have had a significant arc.  I unwrapped both connectors so both bolts had the legs facing away from the dead-front, creating a good ½” of clearance and then wrapped them more carefully.
