Open - answer An____ circuit conducts no power
Tag out - answer When removing power from a circuit so that it can be worked on, be
sure to_______ the switch to ensure that power is not applied to the circuit while you
are working.
automatic - answer An ______ switch is a switch that is controlled by a mechanical or
electrical device rather than by a person.
Throws - answer The number of ____ throws indicates the number of different circuits
that can be controlled by each pole in a switch.
Double break - answer A ____ switch breaks the circuit in two places.
