23、 Scope This European Standard applies to phase couplers in a mains communication system for phase to neutral voltage not exceeding 250 V a.c. and a nominal current not exceeding 125 A, intended for household and similar fixed installation including residential, commercial and light industrial buildi
24、ngs. This European Standard applies to phase couplers used to control the coupling of communication signals between phases or sections of a mains communication system. A phase coupler may be used to achieve coupling between the phases of a multiphase installation, or to provide bridging of signals a
25、round other system components. The standard defines the requirements to ensure a minimum coupling between the sections, and the requirements to ensure no change on the safety of the electrical installation. 2 Normative references The following referenced documents are indispensable for the applicati
