NR - TI 033 ISSUE 1 - DOUBLE CUTTING OF BACK CONTACTS IN SAFETY CRITICAL CIRCUITS Organization: NR
Date: 2006-06-01
Description: GI/GN7517 details the measures to be taken to prevent such a risk and also lists some situations where double cutting may not be appropriate. In a recent issue of typical circuits for LED signals, the decision was made to double cut the feeds to signal heads since this provided a safety benefit, however this was applied to both front and back contacts.

IEEE C62.41.1 - GUIDE ON THE SURGES ENVIRONMENT IN LOW-VOLTAGE (1000 V AND LESS) AC POWER CIRCUITS Organization: IEEE
Date: 2002-11-11
Description: The 1980 version, based on data available up to 1979, proposed two novel concepts:1) The reduction of a complex database to two representative surges: a new “Ring Wave” featuring a decaying 100 kHz oscillation, and the combination of the classical, well-accepted 1.2/50 µs voltage waveform and 8/20 µs current waveform into a “Combination Wave” to be delivered by a surge generator having well-defined open-circuit voltage and short-circuit current.2) The concept that location categories could be defined within an installation where surge voltages impinging upon the service entrance of an installation or generated within an installation would propagate, unabated, in the branch circuits, while the associated currents, impeded by (mostly) the inductance of the conductors, would be reduced from the values observed in circuits located close to the service entrance to lower values observed in circuits located at the end of long branch circuits.
