Interesting. I don't know if this matters or not but due to the amount of heat made by the electronic ballast from overdriving it, I modified the fixtures so that the ballast is mounted on the outside (top side) of the fixture. I don't see why this would be an issue vs being enclosed as the ballasts are still grounded into the fixture and into the ground wire.
So the hypothesis is that current is leaking through the fixture, into the rack, and then...?
Forgive me as I'm 50% ignorant to this stuff so I'm trying to clarify...
A current leaking out from one of the fixtures has to be the cause of the GFCI tripping correct? Since I have 14 gauge wire attached to the shelf at one end and wrapped around the ground of the 3 prong plugged into the GFCI at the other end, how is the GFCI tripping? Shouldn't all the leaked current be going to ground?
Uggh..
Next question, is there a way for me to check each fixture while under load for current leakage via a multimeter?
Sorry if I'm rambling I'm exhausted. I appreciate all your help.
