En suite lighting not going on .

[Amull91]

Guys looking for a bit of advice. Our Mcb on the consumer unit was tripping constant even though nothing was plugged in. Both bedroom lighting and en suite lighting come under this MCB. However until recent both bedroom lighting remain on and the mcb doesn’t trip but the en suite lighting won’t come on at all ? Is there any idea how to fault find before calling in a spark .

Cheers
A

If the mcb is tripping then a significant fault has occurred which has now caused a failure to the ensuite part of the circuit. You are going to need an electrician.
