my RCD is tripping intermittently. I have power circuits and a solar PV installation protected by the RCD. RCD tripped today with no change in load on the circuits i.e. fridge, freezer, TV (on standby) were all on and it tripped without any new load
do solar PV installations potentially cause RCD problems?
given it happens intermittently with no additional load, is this most likely to be a faulty RCD?
