Installation Rules (Paper 1)
Get exam-ready for Installation Rules Paper 1 with searchable chapters written around how the national paper is set. On the legislation side you’ll work through key parts of the OHS Act, the Electrical Installation Regulations (including certificates of compliance and registered persons), the Electrical Machinery Regulations, and the Construction Regulations that apply to electrical work on site.
From SANS 10142-1 the chapters cover fundamental requirements, special installations and locations, estimated and connected load, IP ratings, electricity supply systems, and Certificate of Compliance / test-report material. Cable selection and installation methods are covered under SANS 10198, with LV earthing under SANS 10292.
Jump from each topic to matching past exam questions, download PDFs for offline revision, and track what you’ve already covered so you always know what to study next.
