Electrician question: grounding a ballast for retrofit light installation

[mike31154]

What brand of ballast are we talking about? I checked the Sunlight Supply site and it appears they offer both Advance & Fulham Workhorse ballasts for their retrofit kits? Or do they have their own brand of ballast? In any case, I'd recommend grounding the case of the ballast, especially if it is metal and I think all of them are. If there's no connection or connector provided, just make your own lead with a terminal lug and run the ground from one of the ballast mounting screws. I don't recall ever seeing a ballast that was not grounded on a properly wired set up.
