The 18th Edition Wiring Regulations was released on the 2nd of July 2018 and was officially implemented on the 1st of January 2019. All installations designed after the 31st of December 2018 must comply with 18th Edition Regulations that apply to the design, installation and verification of electrical installations, as well as to the additions and alterations made to existing ones.

We have worked with leading suppliers of electrical equipment to compile a summary of the main regulation changes. Some topics covered include arc fault protection, surge protection, cable management and fire safety.
