This guide explains the main points to consider before speaking to an electrician. It is general information rather than a diagnosis of a particular installation.
What the RCD is doing
An RCD monitors imbalance and disconnects the supply when leakage may present a shock risk. Repeated operation means the cause should be investigated rather than the device being held on.
Possible causes
Damaged appliances, moisture, cable faults and combined leakage from several items can all contribute. Intermittent faults may depend on weather, heating cycles or a particular appliance.
Useful information for diagnosis
Note which circuits are affected, the time of day and what equipment was operating. Do not remove covers or bypass protection to test the problem yourself.
When to speak to an electrician
If the issue involves heat, smoke, burning smells, visible damage, exposed live parts or protection that trips repeatedly, stop using the affected equipment and seek professional advice promptly. Do not remove covers or bypass protective devices.
Getting a clear next step
Share the property type, postcode, symptoms or planned result and any useful photographs. A focused description helps establish whether advice, an inspection, fault finding or a quotation visit is the right next step.
Electrical fault finding
Methodical diagnosis for tripping circuits, lost power and recurring problems.
