A consumer unit and a fuse board serve the exact same purpose (a means of origin for the electrical cabling to be protected and isolated via selected devices (MCB’s, RCBO’s & fuses) within your home). A fuse board is the older term as the board would house ‘fuses’ to protect the cabling. Fortunately, technology has improved over the years and that is why you will tend to see MCB’s (mini circuit breakers) or RCBO’s (residual current devices) installed within your home.
A consumer unit is at the heart of your electrical installation which is why we at Sol-Lux Electrical believe and understand that it should be kept ‘healthy’ and in check with current regulations.
