Electricity is part of our lives. We use it from the moment we wake up and throughout the day. As a result, we sometimes forget how powerful and dangerous it can be.

What to do if an RCD trips

It can be a nuisance when an RCD trips but it is a sign that a circuit in your property is unsafe.  The most common causes of RCD tripping are faulty appliances but there can be other causes. If an RCD trips i.e. switches to the ‘OFF’ position you can:

  1. Try resetting the RCD by toggling the RCD switch back to the ‘ON’ position. If the problem with the circuit was a temporary one, this may solve the problem.
  2. If this does not work and the RCD immediately trips again to the ‘OFF position,
    • Switch all the MCBs that the RCD is protecting to the ‘OFF’ position
    • Flip the RCD switch back to the ‘ON’ position
    • Switch the MCBS to the ‘On’ position, one at a time.

When the RCD trips again you will be able to identify which circuit has the fault. You can then call an electrician and explain the problem.

  1. It is also possible to try and locate the faulty appliance. You do this by unplugging everything in your property, resetting the RCD to ‘ON’ and then plugging back in each appliance, one at a time. If the RCD trips after plugging in and switching on a particular appliance then you have found your fault. If this does not resolve the problem you should call an electrician for help.

Remember, electricity is extremely dangerous and all problems need to be taken seriously and never ignored. If you are unsure it is always best to call the experts. So if you need help with a tripping RCD or if you need to upgrade to one with RCDs please get in touch.
