I find tie wire far superior to even the best quality tie wraps
for supporting bx to chain. I use mostly aircraft cable
for hanging fixtures and tie wraps simply don't work as well for this
and they are combustible.
Regarding the stranded wire issue, cables such as cab tire
may not conform to building codes as far as being combustible etc so
they are only tolerated in very short lengths in non combustible buildings.
Does anyone know if there is a flexible cable that is approved for this
application. I notice that fluorescent fixtures meant to be cable hung come with a piece of white cable that looks far better than an ugly piece of bx.
I think that movement of a hanging fixture is rare so solid wire is suitable
and trying to find a code rule that prohibits it is counter productive in real
practise but reasonable for discussion.
I hope there are no inspectors who would actually reject this practise.
