Yes, you can reset your RCD yourself in most cases. It's a simple process that involves sliding the switch back to its original position. If the RCD trips once and resets without any problems, it's usually safe. However, if it trips again immediately or repeatedly, it indicates an underlying electrical problem that requires professional help.
What is a ground fault circuit interrupter and why does it trip?
A ground fault circuit interrupter is an essential safety device in your electrical system that protects you from electric shock and fire. It monitors the current flowing into and out of a circuit, and if it detects an imbalance of just 30 milliamps, it will interrupt the current in milliseconds. This occurs when current leaks out of the normal circuit, such as through a damaged wire or a faulty appliance.
The RCD trips for several reasons. Moisture is a common cause, especially in bathrooms, kitchens, or laundry rooms where water can get into electrical outlets or appliances. Worn or damaged electrical appliances can also cause current leakage when the insulation deteriorates over time.
Other common causes include:
- Overloading the circuit with too many appliances at the same time
- Damage to wires behind walls or in appliances
- Old installations with reduced insulation
- Lightning and voltage variations in the power grid
When the RCD trips, it is doing its job of protecting you from dangerous situations. It is a sign that something is not right in the electrical system.
Can you reset the RCD yourself without risk?
Yes, you can safely reset your RCD even after it has tripped. The process is simple and requires no special tools. Go to the fuse box, find the RCD that is in the tripped position, and slide it back to its normal position. You will hear a click as it engages and the power returns.
Before resetting, you should take some safety precautions. Unplug electrical appliances in the area affected by the power outage. This is especially true for appliances that were in use when the RCD tripped. Also check for any visible signs of trouble, such as wet areas, damaged wiring, or a burning smell.
A single trip is usually not dangerous. If the RCD trips once and remains reset, it may have been a temporary event such as a lightning strike or a brief power surge. You can continue to use the power as normal.
Repeated trips, however, are a clear warning sign. If the RCD trips again immediately after resetting, or trips several times within a short period of time, this indicates a real electrical problem that needs to be investigated by an electrician.
What do you do if the RCD trips again after resetting?
When the RCD keeps tripping, you need to systematically find the cause. Start by leaving all appliances unplugged after you reset the breaker. If it stays on with nothing plugged in, the problem is probably a specific appliance and not the installation itself.
Then reconnect the appliances one at a time, waiting a few minutes between each one. When the RCD trips again, you will know which appliance is causing the problem. This appliance should not be used until it has been repaired or replaced.
If the RCD trips even without anything connected, it indicates a fault in the electrical installation . This could be damaged wiring, moisture in the walls, or problems with the RCD itself. Such situations require professional help immediately.
There are dangerous situations where you should never attempt to reset the switch yourself:
- If you see smoke or flames
- When there is a smell of burning plastic or rubber
- If there is visible damage to the fuse box or sockets
- If the RCD is hot to the touch
In these cases, you should turn off the power and contact an electrician immediately.
When should you contact an electrician instead of fixing it yourself?
You should contact an electrician when your RCD trips repeatedly for no apparent reason, or when you notice signs of serious electrical problems. Professional help is needed to ensure that your electrical system is safe and functioning properly.
Clear signs that you need an electrician include a burning smell coming from electrical outlets or fuse boxes, hot electrical outlets that are unusually warm to the touch, or visible damage such as scorch marks, melted parts, or cracks in electrical equipment. These are serious warning signs that should not be ignored.
Ignoring repeated trips or attempting to bypass the RCD is extremely dangerous . Some people try to tape over the breaker or disconnect it completely, but this removes the only protection you have against electric shock and fire. The risk of serious injury or fire increases dramatically.
An electrician will professionally diagnose the problem by:
- Measuring the insulation resistance in the circuits
- Test the ground fault circuit interrupter to ensure it is working properly
- Inspect all connections and wires for damage.
- Identifying the source of the power leak
- Make necessary repairs or replacements
Professional diagnosis ensures that both the symptoms and the underlying cause are addressed correctly.

Vanlige spørsmål
How often should I test the RCD to ensure it is working?
You should test your RCD at least once every six months by pressing the test button, usually marked 'T'. If the circuit breaker is working properly, it should trip immediately when you press the button. If it does not respond, it must be replaced by a qualified electrician as it no longer provides the necessary protection.
Can I use an old RCD, or should it be replaced after a certain time?
The RCD has a lifespan of 10-15 years, but can wear out sooner depending on usage frequency and environment. If the breaker is over 10 years old, or if it trips for no reason or does not respond to the test button, you should have it evaluated by an electrician. Older breakers may lose sensitivity and not provide adequate protection.
What is the difference between a ground fault circuit interrupter and a regular fuse?
A regular fuse only protects against overload and short circuit by breaking the current when too much current flows through the wire. The earth leakage circuit breaker, on the other hand, detects current leakage and specifically protects against electric shock and fire hazards by reacting to even small imbalances in the current. You need both types of protection in a modern electrical installation.
Can I install an additional RCD in areas with high humidity?
Yes, it is actually recommended to have separate RCDs for wet areas such as bathrooms, laundry rooms and outdoor outlets. This provides better protection and makes it easier to identify problem areas when a breaker trips. An electrician can install the additional breaker and ensure it is properly sized for the area.
Why does the ground fault circuit interrupter trip during a thunderstorm?
Lightning and thunderstorms can cause sudden voltage spikes in the power grid, which the RCD perceives as a fault and therefore trips to protect the system. This is a normal reaction and the circuit breaker can usually be reset after the thunderstorm has passed. For additional protection, you may want to consider installing a surge protector in addition to the RCD.
Can the ground fault circuit interrupter trip if I have too many appliances connected at the same time?
Yes, overloading can cause the RCD to trip, especially if several power-hungry appliances such as washing machines, dishwashers or heating elements are used simultaneously on the same circuit. The solution is to spread the consumption over several circuits or upgrade the electrical system. An electrician can assess whether the system is adequately sized for your needs.
How much does it usually cost to have an electrician repair ground fault circuit interrupter problems?
The cost varies depending on the nature and extent of the problem. A simple replacement of a faulty RCD typically costs 2000-4000 NOK including labor and parts, while more extensive troubleshooting and repair of electrical installations can cost more. Urgent assignments outside normal working hours often have additional charges. Call 24 Center for a specific price quote based on your situation.
