Completion Certificate (>=50kVA)
The Irish Electrical Completion Certificate (No. 2) is the equivalent of the No. 1 certificate for larger installations with a supply capacity at or above 50kVA, typically covering commercial, industrial, and large-scale developments. In addition to the standard installation details and circuit schedule, it captures supply capacity, maximum demand, and main distribution board details. It certifies compliance with I.S. 10101 and must be issued by a Safe Electric registered contractor. CertBox produces the supporting test record; the Completion Certificate itself must be issued through Safe Electric's Electronic Certification System (ECS).
