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.
Let's look at the facts, rather than making assumptions and firing assertions off in places they don't belong.
A conveyor system is very likely to be "Machinery" as defined. It's probably not even within the scope of BS 7671.
If it is, BS EN 60204-1 applies.
Unlike BS 7671 (or any "guide" book for general electricians using that standard), BS EN 60204-1 has a requirement for the majority of structural parts of the machinery and/or electrical equipment to be bonded (Clause 8.2.1), except in special cases where Clause 8.2.5 applies.
So it might hinge on whether you class the unistrut as a structural element of the machinery or the electrical equipment of the machine.
