As we are now all aware the new IET BS 7671:2018+A4:2026 18th edition is due in April.
The additions and alterations will be indicated by a side bar in the margin, however the other publications (Guidance Notes 1-8, On-Site Guide) don't follow this rule, should they?
I feel this would help electricians and lecturers like myself to identify relevant changes that are not always present in BS7671.
