Bonding both sides of an swa cable

Is it necessary to bond both sides of an armoured cable if it’s not being used as a CPC and if you bond it at the supply side of an electrical motor starter panel is there anything in the regs where it should be bonded too or can it just be bolted to the chassis stud using a 6mm fly lead off the gland. 


thanks for your help in advance guys.

  • Well I would not disagree chaps, firmly with you that it should be earthed. Take the golf club example. The swa cable is in a Wavin duct underground for the full route so 522.8.10 does not apply. The wire armour is not earthed but is taped up albeit inappropriately. Quoting regulations that are infringed is, of course, important, but an inspector carrying out a periodic inspection has to form a view on whether or not danger arises. If this was a new installation, the contractor would be back but I am inclined to consider the risk as tolerable and will only mention it in the interest of ensuring that any further installation activity is appropriately compliant.
