Why do my RCDs trip out – nuisance tripping?

Some electrical appliances and old wiring may have a normal small amount of earth leakage which can trip a RCD.

This is more evident with old lighting fixtures that have iron core ballasts and when combined with a number of other light fittings, this gives a combined earth leakage greater than the RCD allows and will cause tripping. This can be solved by replacing the light fixtures with more modern LED type

Earth leakage increases with each additional electrical appliance that is plugged in, and if RCD keeps tripping out it may be an overloaded circuit. Any faults we recommend that you have your wiring and appliances checked by an electrician to ascertain the fault if a RCD keeps tripping.
