Wiring – How to Ground Lamp and Ballast Properly

wiring

Greetings to DIY community,

That's my first DIY experience, and I literally have zero experience with electricity. I would appreciate any advice if I am missing or doing something wrong here.

I am trying to wire a Philips TUV 55W PLL lamp with a WH43-UNV-L ballast according to the Fulham datasheet (diagram. 12). I know that this ballast is discontinued for now, but at least I managed to get it at this time.
In addition, I know that this lamp type expects programmed start instead of instant start one.

The documentation states "This ballast case must be grounded".

Let's say I am going to use this type of cord, would attaching "green" wire to the ballast's box would be enough to be "grounded"?

Thank you!

Normally the cord attaches to the fixture or to a multiwire splice that connects to the housing and to the ballast if the ballast has a grounding wire or terminal. If the ballast doesn't have a ground wire or terminal the ballast is just grounded to the fixture housing by it's mounting screws.

The ground wire on the cord usually attaches to a designated (green) screw on the fixture frame. If the ballast has no direct ground connection then you can use a blue (for #14 and #16 wire) stake-on fork on the stranded wire from the cord and attach it directly under the ground screw or you can wrap a short piece of solid green or bare #14 wire around the screw and attach it to the cord by a wire connector.

If the ballast has a ground terminal or wire that connection is not adequate to ground the whole fixture by that ground connection. Normally you would connect a short piece of bare or green #12 or #14 wire to the fixture ground screw, then use a wire connector it to the ground wire on the cord and the wire grounding to the ballast.
