Life Hack: What is a trip switch and how can I fix it when the power cuts out?
Over Circuit Leakages Switch A Electricity 30 Current Detects The Of Milliamps From Trip
The ESB says trip switches (RCDs), which are found on distribution boards, are essential safety features in all homes. They make your electrical installation safe if a fault occurs.
A trip switch detects leakages of electricity current over 30 milliamps from the circuit. Once a fault is detected, the circuit is disconnected by a trip switch turning off. They are found in the fuse board and should be tested frequently to ensure they function appropriately.
There is a test button on all RCDs in Ireland — generally the button with a ’T’ written on it. When you press the test button the RCD should trip. The ESB recommend this test be done twice a year: an easy way to remember to do this is to coincide the testing with when the clocks change in spring and autumn.
If you have no electricity supply to your home, first check if your home is the only one without power in the area or if there is a fault in the area. If the fault is not listed, you can report it to the ESB.
If it is not a fault, you will need to go to your fuse board and check whether your trip switch is in the 'on' position or if your fuses have blown. If your trip switch has tripped or a fuse has blown, turn off all your appliances before resetting the switch or replacing the fuse.
A process of elimination will help you to discover what caused the switch to trip, so once you discover what caused it you can reset the trip switch.
If you have an outside meter cabinet with a circuit breaker, check that the switch is in the correct position there too. Circuit breakers were installed in all domestic houses built since 2010.
After following through with these checks, if you are still without power you may need to contact the ESB on 1800 372 999 or 021 2382410. Please quote your MPRN if possible, this is the 11-digit number starting with 10 that is printed on your electricity bill.
If the problem is caused by a fault in your home's wiring, the ESB Networks will not be able to repair it and you may need to contact a registered electrician.
You can plug a portable RCD into any socket. Both the person using it and any appliance or tool connected to this will be protected. It is useful for gardening or DIY jobs taking place outside your home.
