Pillar lights

[keniff]

Hi guys, been asked to second fix some pillar lights and the lights are standing lanterns, basically got 2 swa 1.5 cables at each point out the top of the pillars so need to earth the armour just wondering what people use to earth it when the lights have nothing to gland into? Can't think of a way

 

[telectrix]

are you using the armour as cpc, or do you just need to earth it? if the latter, you only need to earth it at the supply end.

 

[keniff]

Yes just to earth the cable, I have a extra core for the cpc, the armoured is earthed at the supply end, but then wouldn't the cable only be earthed to the first light?

 

[telectrix]

ah, yes. adaptable boxes at each light if possible. if plastic boxes, banjos and fly leads. if cables are inside pillars, i have seen jubilee clips and fly leads used. alternatively a bs951 clamp could be used. corrosion would be your biggest problem .

on pillar lights ive seen, there is a gland plate either bolted or welded onto the inside of the pillar. you then take the inner sheath into the light itself. if the glandplate is welded on, its an absolute nightmare to do, but if its bolted, you gland the cables onto the plate, and bolt it back in

Also , i have seen the armour striped back, twisted together, wrapped in green /yellow sleeving.
I use the seperate box method, and them external flex from there.

Yeah thanks everyone, I have the 2 cables coming out of a flush cemented pillar so needs to go straight into light, clamps sound good never thought of that

I hope your not intending to clamp direct onto the SWA, thereby crushing the inner cable sheath and cores together, ...Now that would be a very, very bad idea!!!

 

[keniff]

No I was thinking of putting an olive from the gland inside the cores of the armour and then clamping!

i've seen it done with a short piece of copper pipe slid under the armour and jubilee clips with a fly lead. this was external , installed about 20 years ago and coninuity readings were still good.

As Telectrix suggested use a suitably sized copper pipe, rather than a gland olive, there just not wide enough to tighten down on, without the risk of the clamp sliding off to one side...

Another way is to gland the SWA cables of as usual with Banjo's or the like, connecting the banjo's together with nut and bolt and a crimped cable lug for your flying lead... This is how i connected my pillar lights in my garden here...

That to me is the way to go.
