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.

    Previous posts are correct from a safety perspective.


    But Mike also mentioned EMC. If the motor is running from a VSD, then it's advisable to bond both ends, using glands that provide a 360-degree bond to the enclosure or motor.


    However, check the VSD and motor manufacturer's installation instructions - as a result of the EMC testing they carried out, they may recommend a higher level of screening provided by:

     - Metal conduit

     - SY or CY cable (but in that case, full 360-degree SY/CY glands are recommended, and see section 7.9 of the O-Site Guide (Page 90 in the latest 2018 edition) regarding selection of cables.
