rcbo tripping

[Lrmurray]

the rcbo for a socket circuit is tripping when i turn on a light that is on a separate circuit. it only trips when there is a load on the socket circuit.

any ideas?

Brush off the dust and get that tester out..
unplug appliances IR test test the rcd

What tests have you done so far?

Sounds like you need to find out what exactly is tripping the rcbo, is it the light Or the sockets

as soon as the light switches on the rcbo trips, the lighting circuit is not an an rcbo, just an mcb. havent tested yet going to look at it tomorrow but i know that is what is happening with it

Switch it on! So is that all the testing you've done and you want help!

i have not yet looked to the fault was just looking for ideas before i do so!

Sounds like the dreaded shared neutrals!

yes my guess would be someone that hasn't got a scooby has been messing around and the most likely place is in the cu ? cant think where else they should have gotten the lighting and the sockets coming together ?

It's an RCBO. Now is it tripping on O/C or E/L, we'll never know untill the OP does some testing. Then he won't tell anyone.
