    12v Downlights not working!!

    I don't know what you are all giving to the scrapman but I just found a docket from a year ago and for 92kg of burnt wire they gave me 419 quid,so 4.55 a kilo.Dunno why yis are all getting such bad prices.

    fire alarm interlink query

    ok thanks for your thoughts....but would that mean that if the circuit breaker was to operate(trip)on my smoke detector circuit,the circuit that I'm trying to control would also drop out?..probably not a major issue....at least they would know their smoke detector circuit has tripped when the...
