Study Question - Grounding Metal Handlhole Lids

[I-learns]

Wondering on something. 314.30D requires bonding of metal handhole lids, for obvious reasons. What happens though, when someone is running cables and not individual conductors. No one would ever strip the casing off the cables to bond. Most sensible thing might be to run a separate ground wire in the conduit and bond to it. However, wouldn't 300.3B might seem to indicate this isn't allowed. Also, 300.3B might indicate a requirement to have a conductor for bonding the lid in each conduit, if there's multiple conduits coming from the source panel.

Also, meant to post this in the general electrical or NEC forum. Probably would have been a better place.
