Fred - I guess this comes from the static discharge straps used in 
electronics. They have a relatively high resistance to prevent the 
wearer suffering adverse effects from accidentally snagging the strap 
on a large source of volts. This might be encountered when 
maintaining or repairing equipment, possibly less likely when 
assembling as volts are generally not applied to stuff being built.

[Of course we didn't have them back in the days when we used to run 
many of our lab oscilloscopes uncased for easy tweaking of the 
calibration, thus leaving 15kV or so available in easy reach of 
anyone passing!]
