Electrics: RCD, sockets and lights
Why your RCD trips, what to do when a socket smells burnt, and when it is truly urgent.
RCD keeps tripping
The RCD trips because it detects an earth leak.
Socket dead
If one socket fails but others work, usually a loose wire behind it.
Lights flicker
Usually cheap LED bulbs or a loose junction box connection.
Socket smells burnt
Cut the breaker and DO NOT use it until inspected.
Flickering lights
Flicker: incompatible LED, loose connection or voltage drop.
Dead socket
Dead socket is usually breaker or loose connection.
Switch broken
Rule out bulb first.
Doorbell silent
Button, transformer or wire.
Ceiling fan
Capacitor or bearing.
Weak WiFi
Relocate + mesh.
