House Electrics Keep Tripping

A Litt • 3 August 2019

This blog has been designed for situations where the electrics keep tripping out. Below are nine steps that homeowners can take before calling an electrician.

RCD and MCB resetting

This procedure can be carried out to determine which circuit is causing the tripping out:
  1. Turn the RCD off (if both RCD’s are tripping turn both of them off).
  2. Turn off each circuit breaker (MCB) that the RCD is protecting.
  3. Turn on the RCD(s) Individually one by one switch on each circuit breaker (MCB).
  4. when turning on each circuit breaker (MCB), the RCD has tripped you have identified the circuit with the fault on it leave this in the off position and turn the RCD back on.
  5. If the circuit is powering sockets go around the house and disconnect all appliances remember to switch off all fused connection units.
  6. Go back to the consumer unit, try to switch back on the suspect MCB.
  7. One by one go around the house plug back in the appliances remember fused connection unit can be turned back on.
  8. When the RCD trips out the faulty appliance is now identified that created the tripping issue.
  9. Unplug the appliance that is causing the tripping and reset the circuit breaker (MCB).
If you are experiencing the RCD tripping at random times or the issue is still happening. 
You would most likely need an electrician to carry out a fault-find.
