3.1Fuse board upgrades
Many older homes still have fuse boards without RCD protection, the device that cuts the power in a fraction of a second if current leaks to earth, for example through a person. Current wiring regulations, BS 7671, require RCD protection for most circuits in a home.
Since January 2016, new consumer units fitted in homes must also have a non-combustible enclosure, usually metal, after a run of fires involving plastic units.
