Friend of Leo's
Thanks for your concern, but this is all approved under Australian Standards for ducting - as long as you have the ground wire running through (which honestly takes longer to sort out than the actual ducting).
Wood dust is highly flammable in the right conditions, but won't burn without a source of ignition. This system won't be used for anything that could generate sparks (it's hooked up to a lathe, a drop saw, and a bench outlet for use with a scroll saw and a belt and disk sander) and the ground wire is there to prevent static build up which could cause sparking inside the system itself.
My primary hobby is knifemaking, so I am very conscious about not mixing dust and sparks. I have a removable collector on a long flexi hose which I can use with my 2x72" belt grinder when I'm working on handles, which will be not just shut off, but removed altogether when I'm grinding steel.
I have worked in a wood workshop and sometimes wood can get so hot while sawing little pieces can get on fire/smolder while traveling/falling in those parts were the dust collects.Thanks for your concern, but this is all approved under Australian Standards for ducting - as long as you have the ground wire running through (which honestly takes longer to sort out than the actual ducting).

so the fire issue i mention t was not about wiring ;-)
once, one morning, we came in the shop and it was full om smoke.
this time not something from the saws etc, but a cloth filled with Danish oil, crammed together ignited, and luckily in a metal bin.
we were lucky that day
