There are some variations of deck boxes. We use Intermatic's PJB series boxes-all plastic. They have a ground bar inside and an external bond lug. Other companies have a threaded brass base and a plastic top. Been a while but I believe same ground bar, bond lug set up. These boxes are applicable for wet niche set-ups. It is to insure the housing/shell for the wet niche is bonded to the junction box grounding bar. Since the EGC for the light is contained in the cord there is no direct contact with the shell if/when the light is removed or should the light become loose and not make good contact. The only thing holding the light in the niche is a single screw.Three sizes of grounding bars and insulated mounting brackets are available.

(D) Nonmetallic Boxes. If there are neutrals spliced in a junction box (floating bus bar or wire nut) the neutral conductor going back to the other panel must be large enough to handle all 120V loads that could be on each circuit connected. ie. Four 120V 20amp circuits spliced into one neutral at a junction box would be ok if that neutral was 4 gauge copper. Grounding Conductors to Boxes. Where circuit conductors are spliced within a box, or terminated on equipment within or supported by a box, any equipment grounding conductor(s) associated with those circuit conductors shall be connected within the box or to the box with devices suitable for the use in accordance with 250.148(A) through (E).
You "sub-panel" use to be a fuse box. Someone relocated the fuses to the circuit breaker box. It's just a junction box now. The top & bottom screws are connected with a bar that is behind the insulator that was left in there. This box should be grounded back to the main panel. If the connection via the water pipe is lost, so is the low .The wires coming into the junction box do not have a ground wire, only the red and black and white.
