Hello James:
As for resistance of the connection, I doubt that there is significant
difference. I have tested both with a high-current-sourcing milliohmeter.
You can repeat the test and see if there is a difference in the resistance.
(Even a loose connection will still pass the high current
James,
If your concerns are above 60 Hz, i.e., you’re thinking about HF bonding as
well as LF bonding for safety, then I have two excellent resources for you:

James,
Most safety standards have requirements for ground bond testing based on
the current available in the hazard. I've never seen
requirements specifying the type of washer other than it cannot have
compressible material in the stack up, as polymers or fiber washers.
Back in the day, I learned
Hello all,
I've given myself a regular internet headache trying to understand the
relative merits of spring vs star washers for use on an earth stud for
protective earthing purposes.
What is the conventional wisdom and justification? I know I can trust you
folks to be above a simple "we've
Hi Douglas,
Glad I could help. :-)
If you are interested in some hard-core debunking of the risk matrix/decision
tree approach, start with [17], [18], and [19]. The authors are not fans of
these approaches as they do not hold up mathematically, even, as you say, many
want them to seem mathemat
IP66 is for harsh outdoor conditions (industrial, offshore, ships, carwash,
etc.)
IPX6 : powerful water jets (water hose :100 liters / minute).
IP67 (temporary immersion in water)
