Old switchboards pose a fire risk due to poor connections resulting from brittle wires and ingress. The older style fuse holders pose an electric shock hazard.
If a switchboard is made from asbestos it must not be altered or modifed in such a way to disturb the asbestoes. Quite often this results in the replacement of the switchboard. All new switchboards installed since 2019 must have RCD protection on every final sub circuit.
If a final sub circuit is installed or altered in anyway than a RCD must be installed in accoardance with the wiring rules.
It is alway recommend old switchboards be replace for new to reduce the risk of electric shock in the household
