Should the unistrut be bonded to the installations metal work. A measurement from the Starter Panel to the metal unistrut reads 0.12megaohms but as the flex is cable tied to it is it a requirement? The flex is ran from a plastic junction box mounted on the unistrut, the flex is ran from the JB to a 110v solinoid approx 1 meter away. Thanks for your help guys.
It’s industrial I work for a water company. the main conveyor is main bonded back to the starter panel and all the cable tray has been supplementary bonded to the conveyer. There was just the uni strut that wasn’t. But if it was measured as having an earth potential I’d have to run a main bonding conductor back to the panel? I’ve seen it before on sites where the cable tray and uni strut are bonded together and sometimes have been linked to hand railing with an earth strap?
I would have thought that WIMES would cover this. Whilst probably not necessary for the reasons given above, you water chaps do like your bonding so I'd bet someone will pick it up and ask why they can't see a bond.
