Question:
Re: CQD answer published Thursday, November 29, 2018 -External Equipment Bonding Jumper
Hi Charlie,
The answer you gave about the external bonding jumper not having to be run straight with the liquid tight flex doesn't appear to match the code words "routed with the raceway". Wrapping the bonding jumper around the flex would not be following the raceway or the wires inside
Thank you,

Answer:
Hey Jennifer thanks for your follow up question. I understand your point but proposal 5-191 for the 2005 NEC, which suggested the practice of spiraling equipment bonding jumpers be prohibited, was rejected. The panel statement was "Spiraling a conductor does not add significant impedance if limited to 6 ft." Even when spiraled around the raceway the equipment bonding jumper is essentially still routed with it.
