As on another thread, smokes on their own or from lighting circuit?

Must admit, i would install them alongside a regularly used lighting circuit.

So what would you do?

As on other thread, try telling that to The Man from Wylex, who says thay should go on their own RCBO.

Local lighting circuit every time
They have a supply which is then much better monitored, because it would be very noticeable if the lights go out rather than an mcb that could be off for ever
 
If you are using a 17th Edition dual RCD board then surely it could stay as a dedicated circuit as it will go out when it's side of the board trips. People would notice half the house is out and know that the smokes are out also??
 
Good point!! It doesn't say that you have to put it on the lighting circuit, only recommends if I remember rightly. Its only my mate was talking about it the other day.

The thing is, I have just finished testing a rewire for my inspection on friday and my smokes are on dedicated 6a supply. Will I fail or will he just recommed I do it differently next time? Dont really want to do another test session as I feel shattered after doing it today!!

Surely if they are on a dedicated supply which trips, then they would beep when the batteries cut in?

Always put smokes on RCBO by the main switch on split board so that if the RCD trips the smokes are still on.I never put smokes on an RCD protected circuit
