where to attach the ESD wrist stap's crocodile clip

Hello and happy new year in advance.
I have a question here. where would be the suggested spot to attach
the crocodile clip of an Electrostatic discharge (ESD) wrist strap. I
was thinking about attaching the crocodile clip to the exposed metal
of any electrical appliances such as my PC's power supply while its
plug remained on the power receptacle. Would this be working?

ATX class computers are supposed to be unplugged when you work on
them, because of the +5 VDC power supply. Find another ground, or make a
cord using only the ground pin to plug into an outlet on your
workbench. My workbenches all have metal outlet boxes and covers, so
it's always easy to find a proper ground.

That will work, so long as your appliance is always plugged in.
Better to get one of the proper ESD earth plug attachments that plug
into the power point though, then you can connect your mat and wrist
strap etc properly in a more permanent setup.

Switch the socket or PSU off (providing it has a physical switch on it,
not too many do anymore)? Or does the US not have switched mains
outlets?

the answer is earth ground . there are many grounds chasiss grounds power gnd signal grounds but the srtap got to go to EARTH becasuse you walk on it. and generate you know what.

Rarely. You can use a switched outlet strip, but for a workbench I
prefer a better grounding system. At my last job we ran #8 AWG bare,
solid copper wire (.12949" Dia.), along rows of benches. We bonded them
to the building's ground system, All joints were soldered, and tested
monthly

Soldering joints is not legal electrical codes. They must be clamped or
use of a legal connecting device like wire nuts, busbar, terminals etc..

Yeah I know, **** off.

In an emergency, if you are wearing natural fibre and leather shoes, its
good enough to clip yourself to the *UNGROUNDED* computer (google
equipotential bonding), just *dont* put any parts down anywhere other
than on or inside the case once you have taken them out of their
antistatic bags. OTOH if you are wearing a polyester shellsuit over
nylon, even wrapping yourself in grounded tinfoil probably wont save
your chips . . . (unless the men in white coats take you away before you
get your computer open)

Well its not for electrical supply or safety ground so how does it come
under the code? Its only for ESD protection ;-)

That lobotomy removed any chance of clear thought on your part,
Jamie. A plant wide ESD abatement system has absolutely NOTHING to do
with the National Electrical Code. It was an entirely seperate system,
with cluster of benches connected to the building's steel skeliton, and
every support column was grounded.

As usual, you sopt nonsense, or ourrright lies to people who din't
know any better.
