The reason I am bought up this topic, it could explain why some people complain about certain earth leakage units "nuisance" tripping for no reason.
If a type AC is install it might not trip when connected to electronic devices, however if for example you are using a type A earth leakage unit, the electronic devices could be tripping the units due to a fault or incorrect wiring.
