answer-Automatic
__________ switching performed by Operators in usually in response to power
outages and abnormal conditions such as overloads. - correct answer-Emergency
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. - correct answer-
manipulation
__________ are electrical switches that are used to manipulate high values of
current and voltage in circuits that are carrying current or will be carrying current
following the operation. - correct answer-Circuit breakers
