RCBO tripping

Anthony Smith

RBCO trips when I switch off circuit, can only reset by closing light switch, circuit has been working normally, suspect condensation but still odd

    Sorry everyone, a bit abrupt, hi all, I have a voltage of approx 25v ac with all LED lamps removed, enough to switch on an LED

    That sort of voltage is perfectly possible due to capacitive coupling, especially with 2-way lighting. What current flows when the circuit is off? (Use fused probes.)

    Thanks Chris, I suspected that may be a reason, why would the RCBO trip when power removed from circuit
