system.
emergency
,Operators use electrical switches to perform routine, automatic, and
____________ switching operations on the electrical system.
Routine
___________ switching is for maintenance, construction, cleaning, testing, etc.
Automatic

possible to limit both the duration and the extent of power outages.
Emergency
__________ switching performed by Operators in usually in response to power
outages and abnormal conditions such as overloads.
, manipulation
The electrical function of switches falls into two categories; ___________ of
relatively high values of current and voltage under load AND the switching of
circuits to provide a visual confirmation of de-energization.
