grounding two (or more) receptacles

[kokonutz]

Quick one , I hope - Today I have 2 receptacles (120 and 220) in my enclosure. I can imagine more in the future. The enclosure is plastic. Is it safe to mount a ground bar to share that ground wire? And if so, what's the best practice to doing so on a plastic enclosure? Is there an alternative to passing the ground?

I did read this post but never got a clear vision of how to pass around the ground to >1 receptacle/component.

Thanks!

Just finishing building my plastic enclosure controller as well. A ground bar is fine for central grounding since theres no conductivity with the enclosure. Just have the power in's ground connect to the ground bus bar, and then everything else that needs to be grounded should tie back to that bar
