Bonding both sides of an swa cable

MrJack96
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.

    OK, but if the armour is not earthed at all, at the risk of stating the obvious,  the cable does not meet the regs requirement for a cable with an earthed armour, and is then to be treated as you would perhaps twin and earth, in terms of safe zones where you can route it and if it needs an RCD at the origin in case it is damaged.


    Given where and how SWA is normally used,  there are few cases where electrically floating the armour makes any sense - if you do not need an earthed armour,  then use a cheaper cable. If you do need it, then earth it


    I have seen the armour terminated not in glands but combed as a 'tail' into large terminal blocks, in much the same way that concentric cables are terminated at DNO fuses etc. It does not provide the mechanical anchor like  a normal gland,  but n those odd  cases where that is not needed, electrically such a termination  can be very satisfactory. (though I like to see heatshrink and there almost never is.) Certainly a tail is better than no connection.
