240 ground question
I don't know how I did not notice this before today, the appliance whip from the hot water tank is not directly grounded to the disconnect, at least not to the ground terminal inside the box.
It is screwed to the wire lock nut on the bottom of the box.
Is the box even grounded to the ground lug through the ceramic plate everything is mounted on?
When the plumber changed the hot water tank a few months ago, he must have left the wiring the way it was, it appears to have been this way for a very long time. Is there any reason this should stay like this?
There is also tape on one of the hot wires, so I would like to shorten the whip, removed the taped section of wire and connect the ground to the ground lug.

If there is a ground lug inside the box then it should be used.
In your picture I see the ground wire but it doesn't look like it goes into the whip that's pictured. Is your water heater connected with BX cable ?

Can I use the locking connector pigtailed to the line and load ground, secured to the ground lug?
Thanks guys,

This is the only label on the box. 
I bet it is older than I am, I think I will just switch it out for a modern box and be done with her.
This should do the trick?
