The 1st of January 2019 was a significant date on the electrical calendar, it was the day we at last saw the implementation of the 18th Edition of the IET wiring regulations. First introduced in July 2018, changes were made across the board as chapters were redesigned, rewritten or indeed introduced for the very first time. Definitions were altered, the scope was extended, and a declaration was made concerning only using the approved parts. Beyond these amendments however, perhaps the most important difference was the emphasis placed both directly and indirectly on green energy.
