Question For Professional Electricians

SIGN FABRICATOR

If I need to ground a printer machine, what is the best way to go about it? I’m not an electrician but I notice that the subpanel I’m working with has no ground. This is a fairly new construction.
The electrician who did the work claims that we need to get the ground from a near JB and to screw the green wire to the JB since is metal and that is the proper way to do it. Is this the proper way to do it or should I find a panel with a ground bar and run it from there?

Thank you,

If this is "fairly new construction" the panel certainly SHOULD be grounded.
This can come from several things, such as the conduit itself.

This isn't meant to be an insult of any sort. With 40 years in the Sign industry and the last 22 as a Master Electrician, I suggest that you have a Licensed, competent electrician do the final connection.

I agree that if this is a new installation, the panel should be grounded. Since you were unable to recognize what was right or wrong in the panel, and the electrician's answer appears to be misleading, I would err on the side of safety and have a third opinion.

I hope this helps, and good luck.
