Reset a tripped switch (consumer unit)

Do this

1. Open the consumer unit (fuse box). Find any switch flipped to OFF / down.
2. Unplug the appliance you think caused it (often a kettle, toaster, or something just switched on).
3. Push the tripped switch firmly back ON / up.
4. If it stays on, plug appliances back one at a time to find the culprit.

If a switch trips again immediately, leave it OFF and stop using that circuit — there’s a fault. Call an electrician (contacts page).

Which switch is which

• RCD (big switch): trips on a fault and can take out several circuits at once.
• MCBs (smaller, labelled): one per circuit — the label tells you what it controls.
• TODO: photograph the unit and label each MCB here.
