Have your say on protective earthing of electrical installations consultation

The British Standards Institution (BSI) has published a draft for public comment (DPC) on BS 7430 Protective earthing of electrical installations – Code of practice.

BS 7430 provides recommendations for earthing of electrical installations, including:

• protective earthing of low voltage (LV) installations to BS 7671;
   
• the interface between LV and high voltage (HV) substations conforming to BS EN IEC 61936-1:2021 within buildings;
   
• protective earthing arrangements for generators running in parallel with a distribution network operator (DNO) or a private HV/LV transformer supplying low voltage installations;
   
• protective earthing and changeover switch arrangements for UPS and generators supplying low voltage installations; and
   
• AC supplies derived from DC supplies, e.g. solar, batteries, wind.

This is your chance to have your say on potential changes that may impact your business.

All comments must be submitted to the BSI by 10 September.

There are also two other draft for public comments currently ongoing:

• PAS 2000:2026 Construction products – Bringing safe products to market – Code of practice: deadline for comments - 18 August.
   
• BS EN 60079-101 Ed.1.0 Explosive atmosphere – Part 101: Principles of explosion protection: deadline for comments - 27 August
