2. Describe why stranded conductors are preferred for connecting the
controller to the diesel engine in a fire pump system.
Stranded conductors have a higher current rating than solid
conductors.
Stranded conductors are preferred because they offer flexibility
and better resistance to vibration compared to solid conductors.
Stranded conductors are easier to install in tight spaces than solid
conductors.
Stranded conductors are less expensive than solid conductors.
