David Garrett, Product Management Manager at Deta, says “This is a reminder that the regulations affecting consumer units become mandatory on 28th September, and that all designers, developers and installers should be mindful that they need to be compliant from this date. Deta can assist in providing related information and product solutions to match your needs.” A house in multiple occupation is a property rented out by at least three people who are not from one “Household” but share facilities like a bathroom or kitchen.

This installation, or part of it, is protected by a device which automatically switches off the supply if an earth fault develops. Test six monthly by pressing the button marked ‘T’ or ‘Test’. The device should switch off the supply and should then be switched on to restore the supply. If the device does not switch off the supply when the button is pressed, seek expert advice. One solution could be to provide an overcurrent protective device within (or external to) the consumer unit, thus limiting the current through the assembly. The assembly will need to be certified by the manufacturer to the relevant part of the BS EN 61439 series and a declaration of conformity to this standard should be provided if requested. Following the release of the 18th Edition Amendment 2 published on 28th March, we have put together a guide to provide everything you need to know on the following areas:RCD testers are designed and manufactured to BS EN 61557-6 Effectiveness of residual current devices (RCD) in TT, TN and IT systems for testing electrical installations. The standard requires that the instrument be able to verify correct disconnection of the supply in the event of a fault but it does not provide requirements for extensive product standard testing. Subsequently, not all instruments will be well suited to carrying out anything more than the most rudimentary of tests. What are the different characteristics of the Type A setting on the test instrument? The type of test is selected on the instrument according to the RCD type. When the instrument setting selected is for an AC Type RCD, the test current applied is a 50 Hz alternating current. However, when the instrument setting selected is an A Type RCD, a pulsed direct current (DC) is superimposed on the 50 Hz AC waveform. Note 1: Completion of an electrical installation designed to the withdrawn standard can be subject to the contractual agreement between all parties involved. Existing installations that have been installed in accordance with earlier editions of the Regulations may not fully comply with Amendment 2 requirements. This does not necessarily mean that they are unsafe for continued use or require upgrading. However, work carried out on an existing installation will need to meet the requirements of Amendment 2 after 27th September 2022. BS EN 81346-1:2009 Industrial systems, installations and equipment and industrial product. Structuring principles and reference designations. Basic rules

BS EN 61009-1:2012+A12:2016. Residual current operated circuit-breakers with integral overcurrent protection for household and similar uses (RCBOs). This applies to the RCD test label, periodic test label, presence of SPD label (new requirement). The only exception is the warning notice of additional supplies which, if required, will still need to be present on the enclosure. BS ISO 3864-1:2011 Graphical symbols. Safety colours and safety signs. Design principles for safety signs and safety markingsThe requirements for RCD testing in BS 7671:2018+A2:2022 are given in the notes to Regulation 643.7.1 for fault protection and Regulation 643.8 for additional protection. A note in each section states the requirements and the key points are highlighted below.

BS EN 61557-6: 2007 Electrical safety in low voltage distribution systems up to 1,000 V a.c. And 1,500 V d.c. – Equipment for testing, measuring or monitoring of protective measures – Part 6: Effectiveness of residual current devices (RCD) in TT, TN and IT systems. Given that an RCD may take up to 0.3 seconds (300 ms) to disconnect it would appear at first glance that some disconnection times in Table 41.1 may not be achievable, for example, the maximum disconnection time for some final circuits on a TT earthing system is 0.2 seconds (200 ms), as shown in Table 3. However, a note under the table indicates that earth faults are of negligible impedance and it follows that disconnection times would be commensurately higher since a value of, for example, a residual current of 60 mA would be expected to provide a disconnection time of 150 ms and 40 ms (0.04 seconds) for a residual current of 150 mA, as shown in Table 2. Therefore, an operating time of 300 ms would be considered acceptable for a TT earthing system. Where there is any doubt about how to use a particular RCD test instrument to verify an RCD designed to operate at 0.25 A the instrument manufacturer should be consulted.domestic (household) premises or similar installations where certification for initial verification, complete with Guidance for Some RCD test instruments however, have an adjustable residual operating current range allowing a value of 250 mA to be set, eliminating the above issue. It is reasonable, therefore, to use a test current higher than the ‘trip rating’ of an RCD regardless of the application of the RCD. The Appendix also recognizes that some of the signs and notices may, in modern installations, be provided on electronic displays, where there are additional standards for legibility.

BS EN 61008-1:2012+A12:2017 Residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (RCCBs). General rules. The person carrying out the testing must identify the operating characteristic of the RCD to determine whether the device should be tested at a current greater than or equal to either 5 Δn or 0.25 A as appropriate. BS EN IEC 61557-6:2021 Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c. Equipment for testing, measuring or monitoring of protective measures. Effectiveness of residual current devices (RCD) in TT, TN and IT system.Regardless of RCD type, e.g. AC, A, F or B, an alternating current test shall be used at the rated residual operating current (I Δn), with a maximum operating time not exceeding 300 ms for general non-delay type RCDs. Whilst BS 7671:2018+A2:2022 doesn’t require other types of RCD testing, however additional tests are not precluded and may be useful for fault finding purposes, these tests could include:
