Flex from FCU to outside lights.

[golfpaul]

Im replacing two outside 100w halogens and re-routing the cables.

Would 1.0mm black flex with crimps be ok to use from fcu to lights?

yes 1mm should be fine but make sure you use a 3amp fuse

I'm guessing you're going to be crimping where the old halogens were and then extending the cable from there?

Would it be too difficult to replace the cable from the FCU? If it would then I'd be putting the joint in a suitable IP enclosure. Personally I'd use wago's in the IP joint box, but if crimping I'd be using a good quality ratchet crimper.

I've thought lots about which cable to use outside and 99% of the time I use black rubber flex (in particular H05RN), however some of the more experienced members are happy with black PVC flex so I have used that on occassion. I suspect the black rubber flex will last for a very, very long time, whereas the black PVC flex will only last for a very long time!

1mm is fine if you are still going to have 100w at the end of them, as long as it is protected by a 3 or 5A fuse... and as long as the current cable isn't 2.5mm if you're crimping!!!

I'm thinking more of 1.5mm2 t&e from consumer unit to fcu, then flex on to the lights.

The crimping i referred to was for the flex into the fcu.

He may mean using ferrules on the flex possibly!

 

[golfpaul]

Indeed he does.

 

[jimjimjim]

Sounds good to me. Boot lace ferrules on the black flex out to the fitting.

[rapparee]

alright boys, what does the abbreviation fcu stand for? fused spur???

 

[ChrisElectrical88]

Fused connection unit.

 

[Guest77]

Indeed he does.

Why? I have never used ferrels connecting a flex into a spur, just twist the cable in your fingers until tight and bend it over, what is this ferrel nonsence about then?

Nowt wrong with using ferrules, so i don't see the point of calling them nonsense.
