SS Bonding Jumper

[jap]

If a meter base is on the front side of a service equipment rack,
And it feeds a panel on the back side of the rack.
And they used 2 standard locknuts and a plastic bushing on the meter side of the rigid nipple (since it was below the parts that would be energized)
And threaded into a Meyers hub on the panel side of the rigid nipple since it was above the main breaker and needed to be waterproof.

Is the SS bonding jumper missing? or do the standard locknuts suffice since the KO's are removed in full on the meter side ?

The Meyers hub has a rubber O ring that would not make it have direct metal to metal contact with the panel, and, it's not made to have a bonding bushing threaded onto it.

1) And they used 2 standard locknuts and a plastic bushing on the meter side of the rigid nipple (since it was below the parts that would be energized)

1) the nipple needs to be bonded with something other than standard locknuts. If there are concentric or eccentric KO's then a bonding locknut on one side is all that's needed. You could also use one bonding wedge or a bonding bushing.

2) The Meyers hub requirement is less definitive, IMO it needs a bonding bushing.
