smoke alarms tripping rcbo

[davidgreene]

Another one fellas,,,,rcbo tripping covering 2 mokes and a heat, IR tests all ok, no continuity between other neutral bars or earth, it did reset, was just about to leave and turned on a light and it tripped.......also tripped when removing neutral from bar,,,,,any thoughts,,,,,worked fine on either rcd side

I think you ought to get an electrician to have a look at it for you.

Smoke alarms now destroyed by 500V+ being shoved through them.

no continuity between other neutral bars or earth,
was just about to leave and turned on a light and it tripped

So very obvious what the problem is.

also tripped when removing neutral from bar

Removing the power first would be more usual.

worked fine on either rcd side

RCBO connected to an RCD? Shirley Knott.

any thoughts

Plenty, but writing them here would result in me being banned from the forum.

Give it a bath!

Are the three detectors on their own circuit, or does it share a lighting circuit?

Are you sure everything is wired correctly, including at the detectors?

Have you got an RCBO fitted on part of the board already protected by an RCCB (RCD)?

What do you mean it worked fine on either RCD? Do you mean you have a high integrity board, and when the RCBO is fitted on the unprotected side it seems ok?

Send photos of everything.

Sparkwright you're making a BIG assumption here that this idiot (who takes baths with his laptop) can operate a camera .

I know, but he may be some young chap still learning stuff. There aren't that many sensible people around anyway.

I think his pictures should tell us a fair bit about this bloke. He may just be a bit naive or something. He may of course be a total nutter, but I expect all will become clear.

You may end up with pictures of bath time!

 

[sparkwright]

He may decide to have a shower tonight...

it's a 15 way wylex rcbo sits on its own, all smokes were removed when ir testing thanks, i moved the circuit to both rcd sides to see if rcbo was being sensitive, ramp tested at 26, checked all connections, i'm not that hot on rcbo's i'll admit but i do test daily and don't normally encounetr things i cant sort out

 

[davidgreene]

they are on their own circuit, investigated the lights

 

[davidgreene]

and guys, please, the laptop jokes getting boring, i have done it for years and never experienced a problem, wont be doing it again though

Can you elaborate on this bit, I don't find it very clear.

Is the wiring new, or old?
