Action:

● Replace the unit if it has old-style wire fuses or cast-iron switches.

● Rewire the entire house if the cables that it feeds are old.

● Even if comparatively new, the unit should be tested by a registered electrician to ensure it provides the necessary protection.

Rewiring

Where an electrical system is outdated, rewiring makes sense. It pays to work in close collaboration with the electrician to ensure that lights and power outlets are installed in the right places and where you need them, and that cables are routed to minimise their physical and aesthetic impact.
