A worthwhile aspect of training [in the US under OSHA; e.g., "1910.331-.335" regs] in the last fifteen years has been for tradesman to be capable of looking at equipment and (safely) determine its voltage class—to avoid deadly mistakes.

To varying degrees, mandatory training is law; to avoid mistakes like applying a 600-volt multimeter to an energized 15kV system…with likely violent consequences.
