Understanding Your Consumer Unit Layout, Identifying Conductors, SPD's, MCB’s and RCD's (fuse box)

In this video we look at the layout of a Wylex 10 way dual RCD consumer unit and explain to appreciate electricians the key elements.

Understanding the layout of your U.K consumer unit (fuse box) including identifying conductors with numbers. We look at the placing of conductor, size and types MCB's, meter tails and the main double pole switch as well as SPD'S and types of RCD AC and A type.
