Supply Protection & Supply Capacity Limitations Interim Guideline' February 2011

Please find the VSIR interim guideline incorporating new requirements to align with changes in the Electricity Safety (Installation) Regulations 2009 invoked on 1st January 2010,

  • Supply Capacity ( maximum demand by limitation ) replaces Supply Capacity clause 6.7 in the current 2005 edition
  • Installation & Supply Protection replaces Service Protection clause 7.4 in the current 2005 edition

Where any conflict occurs in the current VSIR 2005 this guideline will take precedence over any conflicting clauses.

These interim guidelines will be incorporated in the VSIR 2011 edition and on the completion of the rewrite a draft will be circulated for comment by stakeholders.
