    For the record, I'm not a lineman. I'm an electrician, but I do work MV on occasion at the Navy where our bases have primary metering. I also have customers that have private poles on their...

    I get to choose my own fall protection and after much research, I went with the Cynch Lok by DBI/Sala. It's not free climbing, but not a super pain either. There are some decent YouTube videos, if...

    I'm not sure I understand your comment about the ties. I can assure you that the conductor on the far left is not in a tie on the insulator, but it resting on the metal arm.

    The more I look at that photo, I wonder why the cables are not placed on top of the insulator versus being tied to the sides. Would there be a reason for this?
