摘要

Tony Jones, technical lead at BG Electrical, explains: "Currently surge protection devices (SPDs) are installed if written into the installation specifications or if the installation is deemed to be in a high risk area, such as for medical or manufacturing businesses, transport hubs or high rise buildings, but this is about to change."Thanks to the introduction of SPDs as a mandatory requirement into the 18th Edition Wiring Regulations for domestic installations that came into force on 1 January 2019, installers now have to carry out a localised risk assessment of the electrical supply at single dwelling properties to determine if an SPD is needed."The risk assessment is based upon the property's geographical location, the amount of lightning flashes per year and how the incoming electrical supply enters the building. All these factors have an outcome which determines if an SPD is required.
