Understanding your Consumer Unit (Fuse Board) Overcurrent & RCD Protection plus Isolation Features

Students training aid on the different elements of a U.K. consumer unit (distribution boards or fuse board or fuse box). This videos talks about switching for mechanical maintenance and emergency switching. The different types of circuit breakers B, C and D as well as overcurrent and short circuit protection. The video breaks down the elements of the consumers unit and shows best practice with things such as identifying of conductors and the need for earth fault protection via a dual RCD (RCCB) rated at 30mA or less.
