National Annexes are the original national standardization documents that contain information on parameters that are left open in Eurocodes for national choice and are known as Nationally Determined Parameters (NDP).
The National Annexes are generally provided by each country's national standards body but may also be provided by a government building department.
BS EN 50110-2 is the second part of the BS EN 50110 series. It covers information about national annexes for the operation of electrical installations.
BS EN 50110-2 provides electrical professionals with information on the national annexes (one per country), which specify either the additional present safety requirements for electrical installations or give the national supplements to these minimum requirements at the time when this European Standard was prepared.
Note 1: The national annexes are summarized by the respective member country.
BS EN 50110-2 on the national annexes for operating electrical installations is applicable too:
In the BS EN 50110-2 you'll find each of the countries which use the Eurocodes/British standard, and where to get a hold of their National Annex documents. Some of them are in English version, though sometimes only the national language(s) are available.
BS EN 50110-2 provides you with all the information on standard documents related to electrical installation, you just need to do a quick search for the specific BS EN 20XX standard for which you're seeking the National Annex.
