Re: K2 & ESD

[bill KE5KWE]

I am building my K2 s/n 6301 in my Travel Trailer.  I
have plugged my esd wrist strap and pad into the
ground port of a GFCI outlet.  I think this is my only
true ground, assuming that the Camp Ground post is
properly grounded.  All of my test quipment say the
post is wired properly as well as the outlet.  Any one
know, if I am correct?

Thanks,

Bill KE5KWE

Bill,

I believe folks are worrying too much about a 'true earth ground' when
considering ESD - it is actually only necessary that everything at the
workspace (including the worker) is at the same potential - it matters
not whether that potential is at Mother Earth Ground potential or
hundreds of volts above it.

So pick a common point (and the travel trailer wiring ground lug should
be good), and connect your wrist strap and anti-static mat cords to
that, and plug your anti-static soldering station into the same outlet.

If there is a fault in the grounding of that electrical post, it can
pose a hazard for you or your family or pets when you touch the trailer
and Mother Earth Ground at the same time, but that is a different story
altogether - it has nothing to do with ESD protection inside an isolated
structure such as a travel trailer.
