I¹m just curious why something like a spring-loaded captive ³finger² couldn¹t be in contact with the door/plate when installed. I¹m assuming here the grounding is for safety, not EMI. In the latter case, the gasket approach is necessary. Also, for safety I don¹t see the gas-tight spot as an issue: a little corrosion or ³gunk² between plate and finger would break down in the event of a line-potential fault to the door/access panel.

The second is more tricky as there can be no electrical components on the panel and no possibility of a live conductor touch it. I would find a way to keep the ground conductor connected but maybe consider ground studs at opposite corners so it has little slack when closed but allows the panel to be set aside without disconnecting the ground.

Do not open attachments or click on links if you do not recognize the sender. Hi Frank, Can you do a longer ground that allows moving the cover to the side? In my experience it is risky to design a system where the ground is routinely disconnected. If you need to design it that way, I recommend using a braided gasket that is partially compressed when the panel is installed. You¹ll need the panel and gasket plated so that there is no corrosion that would increase the contact resistance since this arrangement can¹t be considered gas-tight.

Hi All, In the past we have typically done a stud and nut grounding for removable lift-off access panels, but this is an inconvenience to disconnect the ground cable. What are other methods for grounding large panel doors (3ft x 7ft) if any? -- Thank you and best regards. - Frank - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
