The funny thing is that usually for industrial plant electricians sometimes
have LESS training than do the residential ones--yet industrial wiring can
be much more involved. Back in my wasted youth working in a steel mill, I
saw an electrician hook up a water cooler (drinking fountain) to 250vdc.
About the smallest fuse used around there was 30 amps--and there was a
bewildering variety of voltages (110, 115, 208, 220, 230, 440, 660...),
phases (1 or 3) and frequencies (25 Hz, 60 Hz or DC).
The electrician sent the slagged cooler back as a "manufacturing
defect--failed on power-on"...
