Cable type for 12V garden lights
My requirement for extra low voltage (12VAC) garden cabling is as
follows: Cores: 2 (red and black, or similar but not blue and brown), flexible. Rating: 6A (max) @ 12V AC Conductor resistance: 0.012 ohms per metre max. Sheath: Suitable for outdoor use (e.g. polyethylene, rubber?) Pro-Power manufacture a speaker cable (http://tinyurl.com/a96zr) which is 62p/metre and has the right electrical ratings. However, it has a PVC sheath which might not take too kindly to puddles (being hygroscopic) or UV. Can anyone kindly suggest an alternative source, please? |

OOI, where did all these very exact raqndom specifications come from? I invented them. Started with the premise that garden lighting cable should be identifiable, weatherproof and low resistance. Local electrical wholesaler. Depending on the exact application then either some UV stabilised flexible cables or any cable of the correct CSA run in conduit would do the job. My wholesalers (WF Electrical and Edmundson Electrical) just boggle when I say UV-stabilised. Some rubber-sheathed flex with the old non-harmonised colours would be good if I could get it in 4mm=B2 |

Perhaps we should tell all the big cable manufacturers to stop using it for all the miles of cable which is in use underground all over the world. UV isn't normally a problem for colours other than translucent or very pale shades. Black is to be preferred. Can anyone kindly suggest an alternative source, please? I'd suggest you go ahead with what you have found. Enclose in a protective tube if you arent convinced its mechanically strong enough |

Standard PVC armoured cable is designated as PVC/PVC/SWA/PVC - Doesn't make mention of anything other than PVC and Steel Wire Armouring on the conductors. YMMV |
