Fuseboard upgrades / Consumer units
Upgrading an old consumer unit to one incorporating two residual curnsider. The 17th edition of the wiring regulations requires most circuits in a domestic property to be protected by an RCD. It is often a better and cheaper option to upgrade the consumer unit rather than alter the existing installation in order to comply with the new regulations.
Swapping the consumer unit may also involve some additional electrical work, to enable the installation to meet the standards set by the new wiring regulations. This might include splitting circuits or running in new cable. An older property might have all the lighting and sockets supplied by just two circuits. It would be better practice to split these so that the lighting and sockets for each floor are on separate circuits with their own circuit breaker. Other problems that require attention include borrowed neutrals. This is where a neutral return path was not available and a link to another circuit has been made. Correcting this fault would, in many cases, require a new cable to be laid back to the consumer unit.
