Now that the regulations for electrics have updated again to the 18th edition amendment 2, as of September 26th 2022 onwards we now must install all our fuse boxes with typa A rcd units and surge protection (spd). This has actually been the norm now for us on all of our fuse boxes since the transition period began back in march 2022. The reason for this in a nutshell is due to all the led equipment that has now become the norm in all of our homes. These new type " A" rcd units will make your property even more electrically safe going forwards. Always remember to use a registered qualified electrical company such as electrician4you. this way you can be assured that your electrical projects are being carried out safely and correctly..
