Introduction\u2026<\/h3>\n\n\n\n

Amendment 1 has been introduced this year to amend\nSection 722 of BS7671:2018 \u2018Electric Vehicle Charging Installations\u2019<\/strong><\/p>\n\n\n\n

It was released on 1st<\/sup> February 2020 and may be implemented from this date onwards. Note: All electric vehicle charging installations commenced after the 31st<\/sup> July 2020<\/strong> will need to comply with Amendment 1: 2020.<\/p>\n\n\n\n

Effects of Amendment 1 on other parts of BS7671:2018\u2026<\/h3>\n\n\n\n

Within Part 2 Definitions<\/strong> there are no changes to the\ndefinitions relating to \u2018Electric Vehicle\u2019<\/strong> on pages 28 and 29.<\/p>\n\n\n\n

New symbols<\/strong> have been introduced (see course handout)\u2026<\/p>\n\n\n\n

Section 722 Electric Vehicle Charging Installations <\/h3>\n\n\n\n

Apart from a couple of minor things there\u2019s only really changes\nto two sets of regulations within Section 722\u2026<\/p>\n\n\n\n


\n* 722.411.4.1<\/strong><\/p>\n\n\n\n

This regulation relates to the methods that should be\nemployed when the installation contains a PME earthing facility (i.e. TN-C-S).<\/p>\n\n\n\n

Firstly, and probably the most common method employed is described\nin point (ii) which has no changes, except that it now says NOTE 3 instead of\njust NOTE.<\/p>\n\n\n\n

Two additional new methods are described in points (iv) and\n(v) as well as their associated NOTES 4, 5 and 6.<\/p>\n\n\n\n

* 722.53 Protection, isolation, switching, control and\nmonitoring<\/strong><\/p>\n\n\n\n

722.531.2 and its associated regulations concerning RCDs have\ngone and have been replaced by\u2026<\/p>\n\n\n\n

* 722.531.3 Residual current devices (RCDs).<\/strong> <\/p>\n\n\n\n

This regulation contains much of the information within the\nprevious 722.531.2 as well as additional information regarding the requirement\nfor 30mA RCD protection including the types of RCD used for the charging points.<\/p>\n\n\n\n

NOTE:<\/strong> This regulation won\u2019t apply if the circuit supplying the charging point is fed via an isolating transformer \u2018i.e. electrical separation\u2019.<\/p>\n\n\n\n

Annex A722 (Informative)<\/h3>\n\n\n\n

Guidance for TN systems where PME conditions apply<\/strong><\/p>\n\n\n\n

A722.3<\/strong> \u2018Earth electrode resistance\u2019. NOTES 2 and 3\nhave been added which are taken from previous A722.4 Notes 1 and 2.<\/p>\n\n\n\n

A722.4<\/strong> the symbols used in the Annex have been moved\nto \u2018Symbols in Part 2\u2019 and it has been rewritten. A722.4 now provides guidance\non monitoring devices described in Regulation 722.411.4.1 (iii)<\/p>\n\n\n\n

Fig A722<\/strong>. This diagram and description have also been\nadded as an \u2018Example of a separated system where protective conductor current\nmonitoring is required\u2019.<\/p>\n\n\n\n

Finally, there is a list of British Standards at the end of the A1 document showing those BS numbers which are referenced within Amendment 1<\/p>\n\n\n\n
