RoSPA NI : Electricity and You
Fuse Boxes
Circuit Breakers
If circuit breakers are fitted in your house, look for the circuit breaker that has operated (opened) and switch off the main switch. After correcting the cause of failure, re-close the circuit breaker, replace the cover and switch on the main switch.
Residual Current Devices
Many houses are now fitted with residual current devices (RCDs). These are sensitive devices intended to operate quickly if there is an earth fault.
A light bulb failure or faulty appliance may cause the breaker to open. If this happens, correct the fault - unplug the faulty appliance or replace the light bulb - and try to close the breaker. If it opens again, remove all the circuit fuses or breakers and replace or reset them one at a time until you find the faulty circuit. Leave this fuse or breaker out and telephone your electrical contractor or Electricity Company for assistance.
Remember to switch off the main switch before replacing a fuse or closing a circuit breaker and do replace the cover before switching on.
Testing
Residual current devices are fitted with a test button. This should be pressed every month to check that the breaker switches off. If it does not switch off, call in an electrician. If you have one of the old voltage operated trips (there is no easy way of telling one from the other, so do get advice if your breaker is old) see about having one of the modern current operated devices fitted.
IMPORTANT
If all your socket outlets and lights stop working, an investigation should be made by your electrical contractor or Electricity Company - telephone them for assistance and remember to ask about the cost. Do not attempt any repairs yourself.
WARNING
If a fuse continues to blow or the breaker keeps operating, don't fit a larger fuse. Try to find the cause or if you have any difficulties call in an electrician.
