Teised raamatud teemal:
The book provides step-by-step guidance on the design of electrical installations, from domestic installation final circuit design to fault level calculations for LV systems.



Updated to include the new requirements in Amendment 3 to BS 7671:2008, the Electrical Installation Design Guide reflects important changes to:







Definitions throughout the Regulations Earth fault loop impedances for all protective devices



Amendment 3 published on 5 January 2015 and comes into effect on 1 July 2015. All new installations from this point must comply with Amendment 3 to BS 7671:2008.
