Have your say! Drafts for public comment coming soon

A number of IET publications are currently in development, with their drafts for public comment becoming available towards the end of the summer.

These include:

  • New publication, Open Combined Protective and Neutral (PEN) Conductor Detection Devices (OPDDs) – OPDDs for Use in Electric Vehicle Charging Applications for Household and Similar Installations.
  • The 2nd Edition of Temporary Power Systems – A guide to the application of BS 7671 and BS 7909 for temporary events.
  • The 3rd Edition of the Code of Practice for Electrical Energy Storage.

Open Combined Protective and Neutral (PEN) Conductor Detection Devices (OPDDs) – OPDDs for Use in Electric Vehicle Charging Applications for Household and Similar Installations

This new standard (also to be known as IET 01) includes definitions, requirements and tests for open PEN detection devices (OPDDs). The device provides, or initiates, electrical isolation in the event of a disconnected PEN conductor in the distributor’s equipment – with specific requirements in relation to electric vehicle charging equipment and installations.

OPDDs are intended to be installed and used in accordance with BS EN IEC 61851-1 and Section 722 of BS 7671:2018+A2:2022. OPDDs to this standard may be stand-alone, or incorporated into other products or assemblies, such as electric vehicle supply equipment or switchgear and controlgear assemblies.

The standard is primarily intended for use by companies manufacturing EV charge points but will also be beneficial to those involved in installation of domestic EV charging equipment and associated products, including, but not limited to, manufacturers, designers, installers, developers and operators. It will also be invaluable to architects, construction firms, facility and estate managers and anyone investing in or responsible for the electrical safety of EV charging equipment and products.

 

Temporary Power Systems - A guide to the application of BS 7671 and BS 7909 for temporary events, 2nd Edition

This updated book is the complete guide to designing, erecting and using temporary power systems for events and similar purposes.

It details the requirements and application of both the relevant parts of BS 7671:2023+A2:2022 IET Wiring Regulations and BS 7909:2023 Code of practice for temporary electrical systems for entertainment and related purposes.

Thorough guidance is given on the planning, design, verification and management of such systems, including references to current legislation as appropriate. It also considers the duties of those supplying equipment as well as venues that make available power supplies for temporary use.

While the focus and examples in the book are geared towards the entertainment and event industries, it addresses a host of topics which are invaluable to any who design, deploy or manage temporary electrical systems.

 

Code of Practice for Electrical Energy Storage, 3rd Edition

This updated Code of Practice is an excellent reference for practitioners on the safe, effective and competent application of electrical energy storage systems. It provides detailed information on the specification, design, installation, commissioning, operation and maintenance of an electrical energy storage system.

The 3rd Edition will also include:

  • An update to the requirements for island mode isolators.
  • Further guidance on fire safety and the location of batteries within an installation.
  • Updates to schematics for domestic use.

Once available, all drafts for public comment will be accessible via the follow page of the IET website: https://electrical.theiet.org/get-involved/consultations/
