Guest Chewie Posted March 4, 2005 Share Posted March 4, 2005 I know this is a big no-no. But can it be done if the mains cable is covered with galvanised steel capping Link to comment https://www.thesecurityinstaller.co.uk/community/topic/5271-12v-alarm-cable-alongside-240v-mains/ Share on other sites More sharing options...

Guest Chewie Posted March 4, 2005 Share Posted March 4, 2005 This is also a cable for a door contact so there will be now power to it. Does that make any difference. I want to run an outside light to the back door and without taking the floor up in the bathroom which I really dont want to do, the only place to run the cable would be chased into the wall just below the coving, but I also need to run the cable to the door contact in the same place.

But can it be done if the mains cable is covered with galvanised steel capping 42443[/snapback] Segragation is what your after. As long as you have a physical barrier between the two or both cable types are designed for the circuit capable of carrying the highest votage. This is from the head filling cabinet, if you want relevent regs BS7671 ask again. Go for it.Jef Customers!

Guest IM_Alarms Posted March 4, 2005 Share Posted March 4, 2005 Electrically the steel capping is a suitable barrier to allow you to run the two beside each other, however unless the steel capping is earthed you will probably still get induction or interference from mains to low voltage/ alarm. This may cause false alarms. As suggested earlier, use screened cable to eliminate the possibility of interference. Good luck Link to comment https://www.thesecurityinstaller.co.uk/community/topic/5271-12v-alarm-cable-alongside-240v-mains/#findComment-42469 Share on other sites More sharing options...

Guest Chewie Posted March 16, 2005 Share Posted March 16, 2005 I managed to keep them 50mm apart, hopefully this will be ok.
