Just to back up E54, look at a motor gland plate. Would you trust it for your earth continuity? Panel gland plates often have a rubber seal. Always a banjo and flying lead to main earth point of whatever bit of kit it happens to be.

A way we used under M&Q was to use two banjos per gland and link them as shown.

You do not need a banjo if the gland is glanded onto bare metal that is effectivley and reliabily connected to the CPC of the equipment. Another alternative is the earthing nuts.

i did mention thats it needs to be reliably and effectivley connected to the earthing terminal of the equipment. On panels that i use, there is almost always an earthing stud, to which a flylead is taken off to the earthing terminal, or chassis of the panel.
to just do away with the banjo, and hope for the best is exactly the opposite of what im saying, what i am saying is that banjos can be ommited, if the gland is tightened onto bare metal, which is then linked reliably and effectivley to earth.

On small CUs and DB's i almost always use banjos because the glandplate cannot be relied on, even when paint is removed.
