Trumpy’s advice is well heeded. A healthy respect for >600-volt gear is always warranted. [As is for <600V gear, too.] There is a phenomenal amount of heat and acoustic-shock energy in electric arcs.
You may not be directly involved with operating >600V distribution equipment, but it still is good to have some understanding of its capabilities in a malfunction. [One source of deadly accidents has been tradesman not identifying higher-voltage equipment, as NOT being 600V-class gear…like attempting to apply a (<1 kV) Simpson or Triplett multimeter to live 15kV-class circuits.]
