Hi Mark,Thank you for your response, I will have to revisit using gaskets and
if there is enough force to have good contact once the door is in place because
there is no locking feature, since the panels are seated in to slots on the
frame.The original design does utilize long ground cables, but when multiple
access panels are opened for maintenance there is no place to lean them and has
to be disconnected form the system. These door panels are the size of a
standard door (~3ft x 7ft) and weight around 30lbs.To your point regarding
safety, there is a concern maintenance or field service may forget to replace
the ground cable, so we are looking at better methods to address both safety
and the human factor.

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. You’ll need
the panel and gasket plated so that there is no corrosion that would increase
the contact resistance since this arrangement can’t 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?
