Reference : C3318 - C3319 - C3320 - C3502 - C3503
The Surge Protective Device (or SPD: generic name for any device that protects against voltage surges) is a recognized and effective solution to the overvoltage problem for any of power or telecom, data, or signal networks. The SPD will be applied between the thread (external network) and the possible victim (sensitive equipment) and will be wired between active wires and bonding network. For greatest effectiveness, however, the SPD must be chosen according to the risk and installed in accordance with the international guides or the local electric codes.
