I have been told that "BS 7671 States that the use of metal cable ties is required for cables of certain gauges". Is there anything somewhere like this in the regs?
The swizzle of SWA armour meets the requirements as written, I rather suspect it was not in the inner eye of the authors of BS7671 as an example of best practice while they earnestly sucked their collective pencils at the drafting stage.
Hello Mike,
I was running some S.W.A. over two vertically hinged rear domestic garage doors yesterday for a garden hot tub. Whilst fixing the cable with S.W.A. cleats I suddenly remembered the requirement to prevent premature collapse of the cable in case of fire. I had some lengths of the steel armour strands to hand and used then in just two positions to make "fire proof" supports. The method is reliable and solid in design. The method complies to Z's standard (133.1.1) and will do the job if required to.
As the location was just an untidy domestic garage, the appearance did not matter too much. But for an OMS upmarket smart city job he would not approve.
