Yup and also on to hold that thing to the wall. Notice the big holes are empty.

Did you notice what four little screws hold that switch to the wall.
What's the capacity of drywall screws?

They look to me like they come out of the CT can and hit the line side(top) and the load leaves the bottom.

Is there a pic of the service entrance conduit into the CT can?

Chris,

If you look real close ( 400% ) to the left of the ground rod, you will see the

PVC pipe going to the cabinet for the c.t.'s

Maybe it's just me but the two white wires in the top conduit appear to be GEC's. If they had some green tape on them instead of white would anyone question what they are?

A sealing lock nut is only listed for RMC and IMC. Also that EMT connector does not appear to be a listed raintite type, the UL standard changed in 2003, I don't know if there are any diecast raintite, I have only seen steel compression raintite.

How about sealing washers?
For use whenever a positive seal is required between the shoulder of a fitting and an enclosure

Sealing locknuts seem to only be for Rigid and IMC not fittings.

Applications

* For use with threaded rigid/IMC conduit to provide a liquidtight seal against water and oil
* RACO? sealing locknuts may be used with either sheet metal or cast enclosures

Is this for real, the neutral for the feeder heading underground is run overhead?


If it is a neutral, should it not be identified within the cabinet? should there be an expansion fitting on the underground raceway?...

There are die cast zinc compression EMT connectors available that are listed as raintight.

Here's one...

I'm not sure if those are #4/0 but you would normally connect your GEC(s) to the service neutral.

The fuse set up is a bit unusual. Is it my imagination that the fuses are not plumb? The bars on the fuses look to be bent? I am not impressed by the fuse connections either.
