Thank you Ted. That was actually a concern of the customer if there is an
arcing. Or for example if unit is broken(damaged basic insulation to PE) and
plugged into the rack. Can it result in hazardous situation?
One thing also bothers me. In hazard based standard there is no requirement for
dis
I would also recommend considering the anticipated voltages on the connector.
Higher voltages are capable of arcing across larger air gaps, and they would
require keeping the ground engaged past the point where the air gap is large
enough to suppress arcing.

The requirement is, as you have quoted, that the
PE connection mate first and break last. There is
no dimensional requirement as such will be a
function of the overall design.
The requirement must be met when mating planes are
not parallel due to the design and tolerances of
the parts.

There is such a huge range of physical sizes of connectors that specifying
'how much longer' would be very difficult.
I think that provided the connector reliably meets ' PE connection shall
make earlier and break later than the supply connections', it is OK.
With best wishes DESIGN IT IN! OOO
Dear Experts,
One customer is designing own connector for hot-plug application (power
supply). Question is how much longer shall be PE pin than supply pins. Which
standard shall be used for such connector?
For reference you can see similar connector on below link.
