unistrut lighting system

[Nigel]

I'd like to see how the cable enters the strut.

I would install FP200 and fit unistrut cover.

Really very simple.

Unistrut can have a cover to the channel fitted. Not sure I would call it a lid.

Unistrut is perfectly fine to carry cables that do not need mechanical protection of steel trunking.

ie. swa, or equivalent…...I've done that, no prob

You can get a plastic lid that clips over the unistrut channel....if that’s any help?

You also get steel lid for unistrut.....and stainless steel 'dairy grade' lids as well.
I also regularly use it as containment for both cables and singles wiring, not sure why there'd be any advantages to using truking over unistrut or why unistrut wouldn't fit the bill admirably as containment.

I have used unistrut for containment before, but not fully. Usually as a stanchion where a cable drops off a tray, and only with sheathed cables. Don't think I'd use it with singles like a proper trunking.

Fair do's....but I use the original strut for fixing to, generally with spring nuts, which obviously prevents using it as a cable route.

 

[Marvo]

If I use it as structural support ie bolted to a wall with cantilever brackets and spring nuts then no, I wouldn't use it as containment in those circumstances.

Suspended from a factory roof with fluorescents fixed to the underside....yep, containment.

Call me a cowboy I don't care

Maybe wrong, but I would doubt it's bs standard rating for carrying single insulated cables. Much stronger than trunking, yes, but what about bushing, locknuts, bends, etc? It's not made for it.

I would not wire singles in it.

I would not wire singles in it.

That's my whole point, Neil. I presumed the wiring indicated was just that.

There's nothing in our local regs preventing it being containment if it's installed accordingly but the UK regs may well not allow it.

There's no pre-formed bends as such, corners and tees are made by hand using a variety of winged brackets bolted on the backside of the strut.
