How to ground electric outlets over a slab?

The OP does not need that ground wire. Oh. I forgot. If he does
not use that ground wire, then he cannot spend tens or 100 times more
money on bud's protector.
w still can't figure out the thread is not about suppressors on 2 wire
circuits. It is about adding a ground wire to existing outlets.
bud is not here to help the OP.
I am a regular on this newsgroup and posted *on topic* before w found
the thread from "surge" on google-groups.
w is here, as always, to spread his religious dogma about the evils of
plug-in suppressors.
He is a sales promoter whose job is to lie and
create confusion.
w is beyond pathetic.
w is the only person who is confused.
OPs either installs a new three wire circuit or uses a GFCI.
Gee - a sentence that is on-topic.
The OP asked how to add a ground wire, which is NEC compliant.
A
properly earthed 'whole house' protector is also required to protect
that GFCI.
UL requires surge protection in GFCI outlets. A MOV connected L-N is
used. How can that possibly protect, w??? No earth ground means no
protection.
And still not answered - how can you possibly protect a flying airplane.
No earth ground means no protection. Is there a massive coverup of
crashes???
And also never answered - simple questions:
- Why do the only 2 examples of protection in the IEEE guide use plug-in
suppressors?
- Why does the NIST guide says plug-in suppressors are "the easiest
solution"?
- Why does the NIST guide say "One effective solution is to have the
consumer install" a multiport plug-in suppressor?
- How would a service panel suppressor provide any protection in the
IEEE example, pdf page 42?
- Why does the IEEE guide say for distant service points "the only
effective way of protecting the equipment is to use a multiport
[plug-in] protector"?
- Why did Martzloff say in his paper "One solution. illustrated in this
paper, is the insertion of a properly designed [multiport plug-in surge
suppressor]"?
- Why do your "responsible manufacturers" make plug-in suppressors?
- Why does "responsible" manufacturer SquareD says "electronic
equipment may need additional protection by installing plug-in
[suppressors] at the point of use"?
- Where is a source that says protection is "inside every appliance"?
- How do you protect airplanes from direct lightning strikes? Do they
drag an earthing chain?
And (with some overlap):
1 - Do appliances and electronics typically have some built-in surge
protection, eg MOVs? Yes or no.
2 - If the answer to 1 is yes, which we all know to be the case, then
how can that surge protection work without a direct earth ground?
3 - How can aircraft be protected from surges, caused by lightning or
static in the air, since they have no direct earth ground?
And still never seen - a link to anyone who agrees with w that plug-in
suppressors do NOT work.
For real science read the IEEE and NIST guides. Both say plug-in
suppressors are effective.
