​I'd check which honey they use.
I'd expect that in Oz by now serious people 'do it right' ​- the standards
tend to proscribe things like cable ties which usually work for 'years'.
Maybe 8 or 4 or 2 or ...
Never 20. Metal ct's get used. Many systems now have wiring clips as p[art
of the panel frame or mounting frame.
