Hmmm.
Not sure. Internally grounded isn't grounded. Its more of a self potential. Going by current NEC code, the neutral and ground are tied together at the CB box. Grounding adds a level of protection. If there is a cap in the ballast system, I'd *seriously* want a true ground. Caps can hole a charge.
I work with 20K+ DC and a big-ass cap. I've been zapped by that cap with the system off, and it just picking up a charge off the static electricity in the air. Something that makes me sit up and take notice.
Just run a ground wire. Same gauge as the power and your cool.
(or just don't touch anything while its on) 2 safest options.
