RCDs switch off the electric supply automatically if there is a fault, giving enhanced levels of safety compared to standard fuses and circuit breakers. It seems that the nuisance tripping may be caused by slight moisture build up during an extended period of inactivity, causing the RCD to activate.
“This issue has been highlighted as operators start to try to reopen,” says Nick Oryino, FEA technical consultant.
“Unfortunately, it’s not something that staff can easily deal with – if the tripping occurs, for safety’s sake you really need to call an engineer in to investigate it before trying to use the appliance.”
