In all of my panels, all control reference legs (115VAC Neutral, 24VDC 0V, 12VDC 0V, 5VDC 0V, are all tied to earth. I've never had a problem.

But if grounding a voltage cause noise on a system, my inclination and little experience would tempt me to look at my ground system more. Is ground noise a common problem that is accepted or not usually remedied? Thanks.
