Protection is recommended for: all cables which enter or leave the building (except fibre optic) the power supply local to important equipment electronic equipment outside the main building(s) Protect incoming and outgoing electrical services Lightning strikes between clouds or to ground (and objects upon it) can cause transient overvoltages to be coupled onto electrical cables, and hence into the sensitive electronic equipment connected to them. To protect the electronic equipment inside a building, all cables that enter or leave the building must be protected. Cables leaving the building can also provide a route back into the building for transients. For each building protect incoming/outgoing: mains power supplies (including UPS supplies) data communication and local area network cables signal, control, instrumentation and alarm lines CCTV, satellite, TV and antenna cables telephone and telemetry lines   1 | 2 | 3 | 4
