Identification of Electrical WiringAs required by Regulation 514.1.2, wiring should be arranged and/or marked so that it is readily identiﬁed for the purposes of inspection, testing, repair or alteration, and each circuit protective device (circuitbreaker, fuse or RCD) should be arranged and identiﬁed so that the circuit protected may be easily recognised (Regulation 514.8.1).
Where it is impracticable to individually label protective devices, the protective devices may be identiﬁed by means of a durable chart or schedule ﬁtted inside the cover of, or adjacent to, the consumer unit or distribution board. Regulation 514.9.1 requires that the form of information provided is legible and durable, and indicates:
For a typical domestic premises and other simple types of installations, a copy of the combined ‘Schedule of Circuit Details and Test Results’, which forms part of an NICEIC Domestic Electrical Installation Certiﬁcate, ﬁxed within or adjacent to the consumer unit is likely to achieve compliance with Regulation 514.9.1. For more complex installations, however, more comprehensive information will be required.
