The IEE Wiring Regulations (BS 7671) are the national standard to which all domestic and industrial wiring must conform. The 17th Edition reflects significant changes to both the technical content and structure of the book. Key changes in the volume include: a change allowing a socket outlet in bathrooms (if 3ms from the edge of a bath or shower and rcd protected); extension of the Regulations to cover new special locations': exhibition shows, photovoltaic (pv) power supply systems, floor and heating systems, marinas and fairgrounds and amusements parks; and, re-numbering and re-structuring of chapters to align with international standards. "The Regulations" move from being the 16th to the 17th edition - a major shift in name and perception of its contents. The 16th edition has been in place since 1991.
