My house was built and wired in the 1980s and has an old-style fuse box. The old fuses have all been repeplaced with cirquit-breakers plugged into the fuse sockets. A couple of people, such as estate agents and electricians have raised eyebrows on seeing the box, telling me it should be changed for a modern RCD unit. Is this true? I've never had any problems with the existing setup, and I rarely get any inexplicable tripping of the circuit breakers. As far as I am aware, the old fuse boxes (even when fuses contained fuse wire) did what they were designed to do, with no problems.
My fuse box has circuit-breakers for: Upstairs ring main Downstairs ring main Upstairs light circuit Downstairs lighting circuit Electric shower circuit External security lights circuit
Obviously, I'd like to avoid the expense of updating it if I'm not under any legal obligation to change anything. Is there really a significant increase in electrical safety with the modern RCD units?
What about if I rent the house to tenants? Will it then need to comply with the latest electrical regulation specs?
THanks for some help.
