IET On-Site Guide
Revised version of the IET On-Site Guide reflects updates included in the latest 17th Edition of the IET Wiring Regulations, this being Amendment 3 to BS 7671:2008.
The On-Site Guide (now with a yellow cover) is intended to enable the competent electrician to undertake electrical installation work on small installations (up to 100 A 3-phase).
It provides essential information in a convenient easy to use form, avoiding the need for detailed calculations.
