I recently bought a PIR operated security light to fit to the outside of my house, the instructions that came with it specify that it should be connected using 1mm2, 3 core flex H05RN-F.
The problem is I can't find this cable any where, I've looked in local DIY stores (B&Q and Homebase) and any internet sites I can think of (Screw Fix, CPC, even ebay).
Does anyone know where I can find this cable?
Possible alternatives? I have found 3 other cables that I can get hold of, I'd be interested to hear your thoughts on these as alternatives.
I'd best tell you a bit about the installation first. The light is a 230W halogen type. I have an existing FCU that used to feed an immersion heater that is now redundant, I plan to fit a 3A fuse to this FCU and run a 1mm2 T&E cable into the attic to a junction box, from here I'll run the cable in question out through the soffit board and down the external wall to the light.
Option 1: 1.5mm2 3 core H05VV-F artic cable, I think this would be ok in terms of rating and safety, however it only comes in yellow or bright blue and would look a bit ugly running down the outside of my house.
Option 2: 1mm2 black 3 core flex H05RR-F, I think this would be ok in terms of rating, but would this be ok for outside use? I believe the RR instead of RN means it has a Rubber outer instead of a Polychloroprene outer.
Option 3: 0.75mm2 3 core pond flex H05RN-F, this is the same type as the flex specified in the installation instructions, however it has a lower rating. It is rated to 6A, am I right in thinking that a 230W light would only draw approx. 1A? if so, I'm confused why the manufacturers would specify 1mm2 flex. The flex will also be protected by a 3A fuse.
Sorry to post such a long question, any advice would be much appreciated.
