To prevent accidental discharge in the event of a power line cross, route on-premise wiring away from power
cables and off-premise wiring, or use a grounded shield to separate the on-premise wiring from the power
cables and off-premise wiring. A power line cross is an event, such as a lightning strike, that causes a power
surge. Off-premise wiring is designed to withstand power line crosses. On-premise wiring is protected from
power line crosses by a device that provides overcurrent and overvoltage protection. Nevertheless, if the
on-premise wiring is in close proximity to, or not shielded from, the off-premise wiring or power cables during
a lightning strike or power surge, the on-premise wiring can carry a dangerous discharge to the attached
interface, equipment, and nearby personnel. Statement 338
