Metal clad heating elements in grills, cookers and immersion heaters go leaky and trip RCDs so that's not unusual.

You can also have some earth to neutral voltage such that a lower impedance neutral to earth fault can trip RCDs even when 'power' is off at a single pole switch like an MCB.

All my RCDs flip the toggle to the off position when triggered.
