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.
"Some customers might still want metalwork to be bonded"
Its always best to bond scenarios like this, industrial, saves problems later, we always expect to see bonding. There is a "guide" type of book, I cant remember the title, which discourages electricians to bond anything, although they have been bonding for 50 years. For example, the anonymous author demands a steel fuse board is unearthed. As the years go by, cables will heat, come loose and short to the unearthed frame.
