Rules for the installation of Over-voltage and Surge Protection Devices
– The correct operation and performance of the SPDs are assured when the ground installation is made in accordance with the official electrical codes, rules and prescriptions determined by the government or by the official entities. – The total length of the connection cables to the SPDs (L) must be as short as possible (<0,5m). – It must be avoided to make derivations in the circuit of the SPDs. With currents up to 50A, the derivations must be made over the same terminals of the SPDs (terminal’s connection capacity: 2 x 20mm2 cross section cables). – The circuit where the SPDs are connected must be protected against overloads and short circuits. It is recommended the use of a MCBs of 32 A - C Curve (C32). – If the installation has different protection levels against over voltages, it is recommended that the length of the cable that connect the main SPDs with a secondary SPDs is greter than 1m, in order to avoid the simultaneous conduction of both devices.
