Shower tripping rcbo?

[whazza22]

It's a non rcd protected mcb board. Rcbo and shower both new. Install for shower circuit approx 10 years

or a socket in the attic spurred off the shower circuit, seen that before.

There's no borrowed neutral as I checked connections in isolator and goes straight to shower

Don't forget that you have changed the circuit protective device, and as such need to complete Eic, and notify the job under part p.
Always do basic tests before touching circuit. If it's unsafe, you were the last person to touch it. At least if you carried out some tests, you can't be liable if circuit is faulty.

use ur tester to test rcbo as u would an rcd! x1/2 x1 and x5!!!!!!!!!
ir test cables to rule out a short!!!!!!
come on bud, u must know this???

I agree with the others as in saying you need to do the tests. But has everyone else not noticed that he says that it only happens when the shower is turned on. My guess is the cable is fine and it is a fault with the shower. This borrowed neutral talk was rubbish as it would trip regardless if the shower was on or off. It does not matter if it is only a new shower they too can be faulty. Don't forget to do a ramp test on the rcbo
