RCBO or RCD trips
If the same RCBO or RCD keeps tripping, stop repeatedly resetting it.

Repeated tripping is usually a warning that something on that circuit or group of circuits needs checking. The useful first clue is the pattern: what was in use, what went off, and whether it happens every time or only in certain conditions.
If the breaker will not stay on, there is heat, a burning smell or visible damage, stop resetting it and use the emergency electrician page.
What this usually means
An RCBO usually protects one circuit. An RCD may protect a small group of circuits. Either way, repeated tripping points to something that needs diagnosis rather than more resetting.
What repeated tripping often points to
- One appliance, accessory or lighting point that causes the trip when it is used.
- Moisture or outside equipment, especially after rain or damp conditions.
- Damage, loose connections or wear in a local point.
- A wider circuit or consumer-unit issue if the pattern is inconsistent or affects more than expected.
What to send for fast fault triage
- Postcode plus a clear board photo.
- 2–4 photos of the affected point if safe.
- A short note on what was in use and what still works.
- Any recent change that lines up with the problem.
What can change the scope
- If the breaker will not stay on, there is heat, a burning smell or visible damage, the issue needs urgent fault triage.
- If wider board or circuit issues are confirmed, the next step may move beyond a simple local repair.
