Electrical techs have advanced to a complex world with the advent of the 
many "uninterrupted power supplies", "standby engine generators with their 
control panel, transfer switch, dummy load etc.", harmonic distortion 
generated now by a multitude of switching type power supplies and 
pre-regulators, etc." and include the variable frequency drive motor 
control, and programming logic control cards where they use a ladder logic 
control language.  I can see where a scope would be very convenient.  I 
believe Fluke makes a piece of hand held equipment that provides a display 
similar to a scope.

I remember when working for the FAA where the electrical technicians were 
rated LWR (local wage rate) while the electronic technicians were GS 
(general schedule) some time during the 80s many electrical technicans were 
converted to GS because of the increasing scope of their field.

I live near a pallet mill (saw-mill) and was amazed at the complexity of the 
motor controls and the concerns of quality power (Third and fifth harmonic 
distortion)
