Grounding directly to hoodless socket

[mrbolloks]

Im wiring a 150 watt HPS and was wondering about the grounding of the socket. All the search results I come up with say to ground it to your hood, but I dont have one. Its going to be a bare bulb hung vertically from chains.

The first pic shows the grounds (green wires) from the wall plug and from the socket, grounded at the base of the transformer. Im uncertian as to where to attach the ground at the socket. Here is what Im was toying with but Im not sure if it is sufficient as a proper grounding spot on the socket

Im wondering about the silver screw on the left in the next pic. On the other side its just connected to a nut with no wires or mounting purpose. The other two brass screws are the white and black wire terminals. Is the silver screw a ground terminal for the socket?

man i dont know for sure but i thought i saw a green screw on that last pic. as far as normal electrical goes green is normally ground wire silver is white wire gold screw is normally black wire. hope this helps.

Yea Im somewhat hip on electrical wiring , its just usually when Im wiring something at work there is always a screw to ground to. Im aware ground wires go like this:

Wall plug ground is grounded to some main ground for all house electricity.

Wire ground from plug to metal housing (ballast is in) which grounds from ballast to actual ground in house.

Ground from ballast to socket/hood which puts the socket, ballast and pigtail to the house ground. All is grounded.

I think I was a bit too stoned when I presented my original question and made it unclear. I guess a better worded question about this would be

Can I just ground to my homemade bracket on the socket?

The second pic is wired with a green ground on my homemade brass bracket (wire is secured to socket mounting screw which my bracket conveniently matches up to). I have just put it there as an example to see if this would be a good spot for the ground wire from the ballast.

Sorry if Im making this more confusing than it should be. My mate just got some Afghan that gets me right fuckered

Having been bit before...

Ground to the bracket, mostly this is to create a separate path should the common go fritz, at least a better path than a human connected to ground through spilled nutes.

Usually three things have to go wrong at the same time before it hurts. In our business that is all too frequent.

yep you should be good grounding to the bracket sir
