What is Consumer Unit Replacement?

Consumer unit replacement involves upgrading an existing fuse box to a modern metal distribution board with circuit breakers and residual current protection. It helps improve electrical safety by disconnecting the power when faults occur, reducing the risk of electric shock and protecting circuits against overloads and short circuits.
