Residual current circuit breakers (RCCBs) are often used to provide protection against indirect contacts in a grounded electrical installation. However, there are situations where the use of RCCBs presents certain problems. In circuits that feed electronic loads usually occur nuisance trips of RCCBs. This article discusses the reasons of the nuisance tripping of RCCBs in this type of circuits based in previous cases studied by the author and some tests performed in a power flexible laboratory. A theoretical circuit used to explain the phenomena is also presented.
