limit both the duration and the extent of power outages. - correct 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. -
