There is also a provision in the regulation that states parties subject to a contract may install to a withdrawn standard. This includes the type of work that involves a long-term project. Main changes One of the main changes in the testing regulations, 643.3, refers to insulation resistance, where the 500 V IR test will be carried out prior to the connection of any equipment that is likely to be influenced or damaged by the IR test. There would then be an additional test at 250 V following the connection of the equipment. This change is made to ensure that the cables are fully tested after erection to ensure they have not been damaged. RCD testing has been revised to include a test of only I 🜂 n, which is the rated residual operating current of the RCD. Appendix 6 Model Forms The forms have undergone many revisions and the new schedule
of inspections for the Electrical Installation Certificate (EIC) has been reduced to 14 items. However, it still includes an example checklist of the items that must be inspected during the initial verification. There are some minor changes to the Minor Electrical Installation Works (MEIWC) and the Electrical Installation Condition Report (EICR) with the inclusion of Arc Fault Detection Devices and Surge Protective Devices. There is a major change to the schedule of test results, which has now been replaced by a schedule of circuit details and a schedule of test results due to the increased number of columns. Installers must pay attention to the changes introduced within the inspection and testing parts, chapters and appendices to ensure the correct initial verification and periodic inspection and testing of electrical installations.

installation, there is a requirement to undertake inspection and
testing of the work prior to, during and on completion. Considering the introduction of BS 7671:2018+A2:2022 Amendment 2, we had to review the changes and incorporate them into our inspection and testing procedures. The model forms listed in Appendix 6 were also being revised, which will result in changes in the current versions of certificates and reports. Chapters 64 and 65 cover initial verification and periodic inspection and testing. Introduction to BS 7671:2018+A2:2022 Amendment 2 became effective in March 2022 and the previous edition was withdrawn on 27th September 2022. Existing installations carried out to an earlier edition may not comply with the current version, but this does not mean that the installations are unsafe or require upgrading.
