Installed a Scantronic 9651 at home, the problem I have is when I power up from consumer unit its trips the rcd also on the consumer unit, the strange thing is the power still remains on on the alarm.

If i remove fuse from alarm problem does not occur, I removed connectors from the low voltage side of transformer to isolate that but it still trips.

Have i got a faulty transformer on the panel or am i doing something wrong.

The consumer unit is crabtree and the RCD is a 30ma, I know that the unit is split but i don't understand how the power can remain on to alarm if thats whats causing the problem.

All help appreciated

have you got your neutrals on the correct busbar ?

have you got your neutrals on the correct busbar ?

There was 2 neutral busbars are these different??

There was 2 neutral busbars are these different??

yep - one for the RCD side and one for the NON RCD side

Sounds like I may have the neutral in the wrong bar then,

Thanks I give it a try in the morning and post the result.

I'm sure you know already but if you don't know what you are doing with mains electricity it can easily kill you, touch the wrong part in a mains board even with the main power switch off and you contact a 80/100A supply that will happily cook you until you die. :!:
