How many down conductors should be installed for lightning protection?

How many down conductors should be installed for lightning protection?

Cost effectiveness is an important but not the decisive factor in the external lightning protection. Saving on quality and quantity of various components, either lightning rods or down conductors, may reduce the efficiency of the whole lightning protection system to zero, while losses after a thunderstorm and repair costs can be much higher than the saved funds. How does it relate to down conductors? Let's settle this issue!
