What may be the reason for an RCD to not reset?


01 March 2021

Usually a faulty load / appliance plugged in to GPO will cause RCD not to reset.
If RCD has all the load removed, and is still not resetting, then the RCD may be at fault and require replacement.
If on the other hand, if removing all loads allows the RCD to reset, eliminate one appliance from the circuit at at time until the fault is found.
