An alarm sounds if a low-voltage condition (____) develops.
below 11.9 volts
If the low-voltage condition continues (for ___), then the shedding of electrical loads will begin.
approximately 1 minute
A shed point is the voltage that will cause a load to be ____ if the system voltage drops to this point.
turned off
An unshed point is the voltage that must be achieved before a load is ___ on once it has been shed.
turned back
A shed system (load) will not be recognized for ____ or until the unshed voltage setting is maintained for____.
