sealing locknut and bonding bushing usage

[SceneryDriver]

Two scenarios:
1) I'm exiting a 3R disconnect through the factory-supplied concentric KO's at the bottom. Do I need sealing locknuts on these fittings? I don't believe so, since I will be below all live parts. A wire-type EGC will be pulled through these conduits. The opposite end of the conduits will be in field-punched KO's in metal enclosures. The EGC will terminate in those enclosures on appropriate lugs. These will be feeder (fused) conductors and so will not need bonding bushings, as the conductors are OC protected and L-to-G voltage is 120V, yes?

2) I'm entering the same disconnect through a field-punched KO on the side, down low (bottom corner), below all live parts. I do need raintight EMT fittings, or a rigid nipple with a sealing locknuts on the outside. These will be service (unfused) conductors from the adjacent meter, and will need a bonding bushing with a lay-in lug on at least one side, yes?



Thanks,

1.; You do not need dealing locknuts on the conduit leaving the #3R enclosure (You might at the termination but you gave no detail on that enviornment or termination)
2. You will need to bond the service nipple on one end .. bushing if concentric or eccentric, bonding locknut if not.

Thanks, Augie. In both cases, the conduit will terminate indoors. I will use a bonding bushing on the service nipple on the disconnect end, and an insulated bushing on the meter end. I will use sealing lockwashers on both ends of the service nipple; I don't need the argument from the inspector...
