MH Wiring Question

[MichaelHall]

Hello. I'm finally growing up (at 40) and replacing my PCs with MHs. I picked up Coralvue 250 and I'm in the middle of installing them. The question: The ballast has 3 wires (black. white and green). The fixture only has white and black. What do I do with the ground wire?

Thanks!

Michael
