If it's a bridge for automotive traffic: you get millions of cars. a fraction of these has damaged spark plug connections. How often would you like to malfunction? | |

But even a nearby lightning strike could induce a significant voltage in the casing, and if that isn't properly grounded, the voltage will propagate down the cable screens instead. | |
