Thanks for the follow-up.
As for PPE ... an experience today ought to give us something to consider.
A six-man crew from the PoCo arrived today, to replace the service drops on my block. (The homes were supplied by wires whose insulation was not sunlight resistant - the maker has skipped town - and was badly checked.) Today was also the hottest day, so far, this year. Temperatures were near 100, and the sun was only slightly dimmed by California smoke.
The crew, to a man, was dressed in long-sleeve shirts, high neck T-shirts, hard hats and safety glasses. While actually working on the energized wires, leather gloves were worn.
I would submit that this ought to be the minimal level of clothing worn when inside a 'hot' panel.
The shirts and trousers strongly resembled standard USN dungarees .... that is, denim trousers and chambray shirts. It should also be noted that, though their work was partly along the roadway, reflective vests were NOT worn. I suspect that there might be an arc flash issue with those.
The services worked on were all 150 amp or less, 240/120v.
