Don’t pay too much attention to that video, there are a few pitfalls! Surge Protection – To meet the requirements of Section 443 in the second amendment of the BS 7671:2018 wiring regulations, such protection must be installed, where overvoltage could: 1. Result in serious injury to, or loss of human life, or 2. Result in failure of a safety service, as defined in part 2, or 3. Result in significant financial loss or data loss. For all other cases SPDs shall be fitted to protect against transient overvoltages, unless the owner of the installation declines such protection and wishes to accept the risk of damage to both wiring and equipment as acceptable.
